Sound Texturizer : YIRUTO

This assignment we are tasked to make a product that produce 3 sound qualities.

I just knew this is my chance to explore magnets. I don’t know how i’m gonna make sound with it but magnets will be my main medium.


This is my initial draft sketch before exploring online.

Upon researching, i found this really cool video and that’s where my source of inspiration come about.


I tried making it but failed. I couldn’t make the CD spin continuously and have that “free energy” flowing through it. Mine is like a spoiled old car that spin only a bit then pause. Spin, pause, spin pause. Even when i increased the amount of magnets, it still the same. Probably spin just a bit more only haha.


I explored a lighter material using plastic container lid and bottom. Using the middle one in the photo give a better result. As the container bottom is lighter and has a smooth protruded center, it aids in the spinning, making it turn longer. Although there is still pauses in between, this is the best i could go for.




I had various ideas to make use of the spinning motion. I could make it like a swing ride, have something attached to the base, so when they collide, they would produce sound in a way like wind chime. I also thought of adding bristles along the side of the rotating disc, the bristles will brush along the edge of the container and produce sound. Basically there will be layers of different sounds.



When i went to art friend, i saw this interesting globe ball that can be separated into half. I thought it would be fun to test it out like a roly poly toy. With this new toy, i thought of various ideas like having a slide circulating the globe. Thus, when the rotating disc hit at certain point, there will be a mechanism that release a ball and it would slide down the slide, producing an echo and Doppler effect. However i feel that this is too time-consuming when i had other assignments to do too. Hence i decided to create different layers of sound instead.


I explored with different materials and textures to see which give the result i wanted.


I wanted sounds that goes well with each other and create a sci-fi music like at 6:48-7:00.



This is my first prototype which i presented in class.


Lots of layers inside.


Now let’s hear the sound individually in each layers.


First up is the capsule that contains a bead and a decorative piece.


Secondly is the capsule rolling around on very crumpled aluminium foil.

I made the shadow of “Ben” Grimm’s face! So cool!



Thirdly is a smoother surface of aluminium foil.



Lastly, is the beads circulating in the slightly rubbery lid.



This is what the capsule sound like without any foils.



Comments from Mrs Cherly: The sounds are very delicate. Maybe can try to extrude out the lid using wire mesh, so the sounds can project out.


Personally, i like soft low pitch sounds. However i feel that my sounds doesn’t have a clear distinct separation with each other because they are all trapped under the thick cardboard lid, a poor conductor of sound. After seeing the class presentation, i realized i should make my sounds louder. Hence off to the next prototype.



Following Mrs Cherly’s advice, i changed the material of lid to a thinner cardboard and extrude it out. I feel that changing into a thinner layer of material has the same effect as protruding out the lid. Hence i decided to go with a thinner layer instead. Ultimately, i choose a pvc sheet so that the inner layers could be seen as well.


Besides playing around with different textures of foil, i also tried experimenting with different beads.

They look so pretty together! It look like i’m doing jewelry photography. 



With this i created a new planet, Yiruto! The tiniest, noisiest planet the mankind ever discover on this universe!


Rolling the bell on foil.


Rolling the bell on foil in bowl container.


Beads and decorative “stars” on top of a rubber lid in a bowl container. Occasionally the metallic beads will bounce up and come in contact with the container and circulate on top of the lid. The friction between the container with the bead produce a unique vibrating high pitch sound.




Witness Yiruto’s Revolving Moments!




After a final consultation with Mrs Cherly, She advised me to lift up the foil a bit so there’s room for the bead to circulate.





How a metallic bead sound make a difference.



Upgrade Version of Yiruto in Action






Special video!


When testing out different bells, i realized some bells are conductor of magnets. This is the strongest among all the bells i tested. There’s a whole new approach of making sound in this video.



Personally, i like the sound of the first version of Yiruto. The chiming bell sound is louder and create a beautiful sound with some occasionally vibrating beads. Then again, the second version fit my sci-fi theme better. Although i feel that the echoy sound could be better improve to fit my theme.





Im really excited for this project when i learned that we have to get our inspiration from animals. We drew lots and i got teamed up with Natasya and Amelia. Each of us had to research on an animal within the classified relationship of symbiosis, mutualism, commensalism, parasitism, etc. Our team decided to work on Sea Anemone and Nemo. Since this is a mutualism relationship, i decided to add some spice by introducing a new relationship. This is what i researched upon.


Eeeeekkkk! When the sea anemone wiggling away to escape, i was so grossed out. That aside, i never knew sea anemone and starfish could move. Hence, the animal i’m researching will be Patrick! The big boss in a predator-prey relationship. I realized parasitism doesn’t quite explain their relationship well because for it to be parasitism the organisms would have
to live in, on, or near each other while one creature benefits and one is harmed.




This video explains everything we have to know about starfish’s anatomy, movement, etc. My job here is done.

Hahaha! Just kidding.

I will explain a bit more on the structure, movement, hunting and senses of starfish.



Sea star or more familiarly known as star fish is an echinoderm, which is an invertebrate that has a proportional radial body. They lack brains and have absolutely no blood. They live by pumping seawater through their bodies to deliver nutrients, oxygen, and other essential fluids. But even without actual red blood, the starfish still has a circulatory system with a heart that constantly beats at a rate of 6 times in one minute. They have tough leathery skin, which protects them from most predators, and many wear striking colors that camouflage them or scare off potential attackers.


Sea stars are like zombies. They can rip off their limbs and in some cases, entire bodies, with the purpose of either escaping from predator or reproducing asexually. They can regenerate their limbs by housing most or all of their vital organs in their arms. Some require the central body to be intact to regenerate, but a few species can grow an entirely new sea star just from a portion of a severed limb.


I wish corn also have regeneration ability so i can eat non-stop. Why only creatures have this ability and not crops? Like that farmers don’t have to work so hard under the harsh sun.


Skeletal Structure


The ring in the center is the Ring Canal. It’s in the central part of the starfish. A Radial Canal runs down the length of each ray, with a row of ampullae and tube feet on each side of it. The ampullae prevents water from flowing back to the radial canal. Also coming off the Ring Canal is the madreporite. The madreporite is like a sieve or strainer, and filters out particles in the water. It allows the water to enter the water vascular system from outside the starfish.




Starfishes are slow-moving creatures, some can actually just cover a distance of less than 10 inches in a single minute. Beneath it, there are numerous rows of small tubes which serves as the feet of the starfish. The vascular system of the starfishes regulates the pressure of the water that exits the legs. As water goes out, the legs are lifted upwards while some of the legs create suction to adhere on their next small steps. At the tip of each tube foot is a suction cup which is only used when walking up sheer surfaces. In a way, their legs actually do the walking motion but they release water and latch on to the surface of the ocean to create traction.





You can see the stark difference in speed between starfish and nemo. And i think the starfish just pooed…


Cool fact: Starfish can make glue

Their feet can form a glue that will bond indefinitely with a rock or prey item, with an adjacent tube releasing a solvent to undo the bond once the star is ready to move on.




  • Sight

Most starfish have eyes on the tips of their arms. It’s a tiny red nub, barely half a millimetre wide. It’s usually exposed, but the starfish can retract it into the arm if danger threatens.



These eyespots are not as complex as other animal’s eyes because they are only contains light-collecting units called ommatidia and lack of any lenses to focus light onto the underlying cells. Each eye has a fairly large visual field that extends over 210 degrees horizontally and 170 degrees vertically. Since the starfish has five of these eyes at the end of its flexible arms, it can probably see in every direction at once. However, its vision is rather poor. It’s colour-blind, and sees the world only in shades of light and dark. Its light-detecting cells work very slowly, so fast-moving objects are invisible to it. Starfish doesn’t need to see colours, details, or speedy objects, because it mostly uses its eyes to detect coral reefs.


  • Touch

On each limb, there may be 10000 over tube feet attached underneath. These tube feet are very sensitive to touch and sensation. These touch receptors can sense pressure, temperature and pain much and also help in determining the temperature of the water so that they can move away from the temperatures that are not suitable for them.


  • Smell

The spines on their backs are also equipped with chemoreceptors, which give them the extremely well-developed sense of smell they use to hunt prey and avoid predators. They can even determine the direction from which it is coming. The starfish then sets off to catch its prey, slowly and deliberately, following the direction of one arm.


Hunting Techniques

Starfishes begin hunting their prey through their keen senses. They can actually detect the presence of a prey’s odor. So when their senses detect prey, the legs begin to act and move to that direction.They are usually slow predators that take advantage of other animals that are slower than them or stationary. If the prey is larger than the size of their mouths such as clams, they use their tiny, suction-cupped tube feet to pry open them. Using pressure exerted by the water vascular system, the cardiac stomach can be pushed outside of the sea star’s body and inserted inside a shellfish. The stomach then envelops the prey to digest it, and finally withdraws back into the body.


In conclusion, sea stars are cute creepily creatures.

And they don’t run like that.

Dialogue in the Dark

We went to Dialogue in the Dark for our class outing. It was my first time going there. I thought it was dine in the dark concept, so i was really looking forward to eating but turned out it was different from what i expected. Haha! Still it was a fun experience.


First off, we begin our journey by getting our walking stick and being briefed upon. We feel our way in the dark, touching the wall as we go. It got dark pretty soon until i can’t even see what’s in front of me. I got a bit scared and feeling my way through the many edges of the long corridor wasn’t helpful at all. Then i began to hear birds singing and water flowing sound. It slowly calm me down. However i wished the audio is better and the birds sound more real. Moving on, i stepped on some rocky path with small pebbles and touched the pandan leaves. It smelled quite good. Then we all sat on the bench listening to the tour guide talking. It was quite squeezed at that time. Then one of my favourite part is the bridge because it swayed randomly. I’m suspecting my teammate for shaking the bridge but that’s all add to the fun bits.

We came across Sir Stamford Raffles which im sorry to say it’s the most unmemorable part in the whole trip that i forgotten to add it in my sculpture. We have to feel the protruded letters on the wall and pieced them up and it formed “Sir Stamford” i think. Now it’s the popular destination: the boat ride! We all got packed in the boat and it starts to move. I can feel the strong wind blowing and water splashes as we passed by many different spots like the Clark Quay, under tunnel, etc. The tour guide narration was helpful for us to visualized better as the soundscape changes.

Leaving the boat, here comes my favourite spot; crossing the traffic junction. I stood nearest to the post so i get to pressed the button. Somehow its felt so strange. Something i been doing all my life yet i felt excited like a little kid when i had a chance to press the button in the dark. We waited for the traffic light to turn red and heard all the cars stopped then we felt the tactile floor and crossed from one to another. That’s was my most exciting moment; without the tour guide telling us what to do and i get to roam free and explore on my own. Then we tried to feel our way around bicycle and car. I got trapped near the bicycle for a while before freeing myself.

Moving on, we touched cold metal shuttle and i felt a telephone and played with the buttons. We came into the market and there’s carts of fruits and spices so i felt the texture and smelled it. However i couldn’t smell anything. Well well, at least i got most of the fruit and spices correct. Hehe. Before stepping into the cafe, there’s bells ring as if signalling our arrival. It brought me to Paris with that bell chimes. It felt like some “atas” cafe. It has some peppery, spicy smell wafting in the air.The space got so big in to cafe as compared to the previous locations. I ordered and paid for my green tea. It took me a while to find and poke the straw into the hole of my packet drink. Then we sat at the sofa and chitchatted with the tour guide. As we leave, the light from the outside seem to pierced my eyes as it got adjusted to the dark.




We are told to construct a sculpture based on the spaces at different areas we experienced.



I curled the entrance because we are briefed in an enclosed area. As we passed through the narrow alley, with lots of turns and edges, i felt a bit trapped because i still have not gotten used to the dark. For the park, i decided to focus on the bridge and pandan leaves, so there are overhanging curls for the leaves. The bridge is a bit swaying sometimes so i made irregular crease to show the swaying motion coming from the sides of the bridge and the straight narrow path is the bridge itself. On the boat ride we all sat close to each other, i used the strips and crumpled it a bit here and there. We passed through different soundscapes on the boat, so there are different space like it felt smaller as we pass through the tunnel and bigger in Clark Quay. The holes represent the wind blowing. For the road, i used small slits to show me trapped in the bicycle. For the market, i crumpled that line because whenever i go to market, it will always be crowded and all my senses are focused on figuring out the fruits. As i got to the cafe, i realized there’s not much space to show the spaciousness in it. If i had more paper, i would still leave it untouched to show huge void of space i felt in the room. I felt small as i leave so i cut jaggedly to show the light piercing into my eyes, making me want to hide.




That’s all for now!



Research: Sound Texturizor Keywords

Sound Conductors

Sound waves travel faster through denser medium. That’s why sound travel faster in water than air. But even more influential than a conducting medium’s density is its elasticity. Elasticity refers to how well a medium can return to its initial form after being disturbed by a force. Steel has high elasticity. It bounces right back to its original shape after an applied force is removed. At the particle level, the molecules in elastic materials transfer energy more efficiently, so sound waves travel faster through steel than through water or air.

I found this video pretty cool. We can play different instruments through air.




She is the daughters of Mnemosyne and is called the “Giver of delight”. In late Classical times she was named muse of lyric poetry and depicted holding a flute.


Destructive Interference


When the crests or troughs of two interfering waves meet, their amplitudes add together. This principle is known as constructive interference. When the opposite happens, and it’s called destructive interference. When the crest and trough of two interfering waves meet, one amplitude subtracts from the other.


This is how a tuning fork works.The piano tuner strikes the tuning fork, and at the same time strikes the appropriate key on the piano. If their frequencies are perfectly aligned, so is the sound of both; but, more likely, there will be interference, both constructive and destructive. In the case of constructive interference, their combined sound will become louder than the individual sounds of either; and when the interference is destructive, the sound of both together will be softer than that produced by either the fork or the key.


Anechoic Chamber


It is the most quietest room in the world designed to completely absorb reflections of either sound or electromagnetic waves. They are also insulated from exterior sources of noise. I wish i can go inside to hear my blood flowing and what sound my body make.


White noise

It is random signal having equal intensity at different frequencies, giving it a constant power spectral density.





Refraction is the bending of waves when they enter a medium where their speed is different. The different of temperature in water also cause refraction. This seem interesting to work with.





Research: Sense of Hearing

How do we hear?




The human ear is divided into 3 parts such as the outer ear, the middle ear and the inner ear. The outer ear is comprised of the auricle and the ear canal. They channel sound waves toward the eardrum. The eardrum passes along the sound vibrations to the ‘ossicles’, the three smallest bones in the human body, then divert it to the fluid-filled, ‘labyrinth’-like structure in the inner ear called the ‘cochlea’, where the true hearing organs reside. The sensory organ for hearing is the “Organ of Corti” containing about 15,000-20,000 specialized sensory cells, each with a tiny hair capable of picking up minute vibrations in the cochlear fluid.  Various hairs are specialized to detect sounds at various frequencies, and turn them into nerve signals to be sent to the brain.


It interesting to see how our ears operate like various instruments put together to produce music in our brain. With the ear drum taking on the drum role, the ossicles on the tuning fork and the hairs inside the cochlea is the shaker. Its lacking a ukulele to make a chill hipster band.


Ear Pressure

Sometimes our ears are blocked when we are ascending up in the sky on the airplane or diving underwater. It is caused by the change of barometer pressure in the Eustachian Tube. The Eustachian tube connects the middle ear to the back of the nose. This tube opens and closes while we swallow or yawn. This movement helps equalize the pressure between the middle ear and the outside environment. If it does not work properly, negative pressure develops in the middle ear leading to ear problems  like a blocked ear. When this happen, we can try to yawn to open the tube.




Cheryl post this question to us and im quite amazed at my findings with this cute little creature.


  • Same Organs

Both frogs and humans have many of the same organs. Frogs and humans have lungs, stomachs, a heart, a brain and livers.



  • Similar Skeleton Construction

Just like in a person’s arms, in a frog’s front legs are bones called the humerus, the radius and the ulna. They have 5 fingers and toes like us too.

  • Hearing Mechanism

They do have eardrums and an inner ear like us. The frog ear is called a tympanum and the size of the tympanum and the distance between them are relative to the frequency and wavelength of the species male call. Their eardrum works like a regular eardrum with one very special adaptation…it is actually connected to their lungs. The lungs vibrate and are almost as sensitive to hearing as the eardrum. This allows frogs to make really loud sounds without hurting their own eardrums!


Bizarre Facts

  • In the early 20th century biologists discovered that African clawed frogs were unusually sensitive to human chorionic gonadotropin (HCG), a hormone produced by pregnant women. Doctors would inject a frog with a woman’s urine, and if she was pregnant, the frog would ovulate and produce eggs in 8 to 10 hours.


  • Frogs use their eyeballs to swallow. Frogs eat their prey whole and their eyeballs actually sink down into their mouth and push the food down into their throat.

Yucks! I can’t look at them in the eye now.

Research: Sense of Touch

Skin is the largest organ in our body so i’m really interested to find out more about it.


How does the anatomy of skin works? 


Skin is made up of several layers. The top layer of epidermis is made of dead skin cells and serves as a waterproof layer to protect our body. It contains melanin which gives human different shades of skin colour.




An interesting yet so disheartening melanin map. What is the issue with skin colour when we are from the same world…


The Dermis layer is where our sense of touch works. The dermis contains hair follicles, sweat glands, sebaceous (oil) glands, blood vessels, nerve endings, and a variety of touch receptors. Our sense of touch is controlled by a huge network of nerve endings and touch receptors in the skin known as the somatosensory system. The touch receptors best sense vibrations occurring  on or within the skin. It then transmit a signal to the nerve system for it to sent the message to the brain and back to the hand for further action. However the receptors are slow at responding to a change in stimulus, so we don’t know when exactly the stimulus start or end.


The bottom layer is the subcutaneous tissue which is composed of fat and connective tissue. The layer of fat helps regulate body temperature and acts as a cushion to protect underlying tissue from damage when you bump into things.


After reading about our touch receptors, i’m curious if i can train my senses to be more acute like ninja!

Apparently we could sharpen our brain and develop mad sensory skills with diligent and conscientious effort!

Superpower obtainable: Echolocation

I can be the whale in Finding Dory detecting where the sound source come from. Haha!



Touch is important for child development.

“If you don’t get touch right after you’re born, all kinds of terrible things happen, and not just cognitive and emotional,” said Linden. “Your immune system doesn’t develop properly, your digestive system tends to have problem — there’s a whole rack of health problems that can develop if you don’t receive touch in early life.”

In the 1950s, parenting manuals advised parents not to touch their children too much — recommending, instead of hugs and kisses, giving kids a “pat on the head.” But Linden warns that touch deprivation denies children a chance to become socially integrated with the people around them.

“A parent’s touch is very crucial for a child’s development,” said Linden. “It’s not optional.”

Touch = love, humans are animal born needing affection. No wonder guys like to pat the head of the girl they like haha!


Chocolate Analysis + Research


Who would expect we get to eat in our first lesson of class? It was an awesome way to start the class! The chocolates I had satisfied my hungry stomach lifting my mood for an early morning. Our task is to use our senses to taste and smell the chocolate we were given and link it to our memory. Before the mini class activity start, the lights were off so our senses will be more acute since our eyesight were blinded. After each chocolate tasting, we were given a small piece of bread to eliminate the remaining chocolate taste before we begin a new piece of chocolate.

Here’s my analysis on the three chocolates I had tasted. I had slight sore throat and blocked nose. I hope my analysis won’t be that far off from the rest. ]


Chocolate A

Feel: Smooth. This seemed like a typical chocolate that can be found in supermarket.

Smell: Slightly bitter and smelled like dark chocolate.

Taste: Hard and slowly break down. Bitter to slightly spicy. The more chocolate I bit, the spicier the finishing taste was. I guessed the spicy come from cayenne pepper.

Memory: As the taste reminded me of cayenne pepper, I remembered my horrible cooking in the past. I added too much of this into my noodle soup and the whole bowl tasted so spicy and not even savory. I had to finish the whole thing because wasting food is bad. This just made my nose leaked the whole time.


Chocolate B

Feel: Textured surface in round shape. It felt like a luxurious chocolate.

Smell: Slightly bitter like dark chocolate.

Taste: The taste was smoother than the previous chocolate. There’s a sour taste. It seemed like alcohol is added in. Unlike the spicy flavor that slowly kicked in and lingered in chocolate A, this sour taste came strong in the beginning and faded quick. At the end after eating, I felt disgusted somehow, my heart had the sicky feeling, not sure why.

Memory: I recalled myself drinking low alcohol percent of red wine. Pretty meh.



Chocolate C (The crowned winner!)

Feel: There are small humps and rougher texture on one side.

Smell: Slight salty savory smell.

Taste: Crunchy. It tasted like hollow air biscuit. The biscuit is light and airy so it gets crushed easily when bite. Initially there wasn’t much of a taste at the start then the sweet and savory slowly appear at the end.

Memory: I was horrified when I touched the chocolate because the humps reminded me of fake spider legs. I was on the verge of throwing the chocolate on the floor. My logical side stopped and calmed me down by telling me, “The last one can’t be some weird shit. It felt like it… but nope it can’t be. She won’t feed us spider chocolate.” Pinning my hope on it as Ms. Cheryl can’t be a psycho. The smell made a 180⁰ change on my perspective. The slight salty savory smell reminded me of a Malay snacks served in a cone paper during my primary school days. My school held some Malay festival so there are booths that sell Malay snacks. I had a lot of fun with my friend trying out things we usually don’t get in our canteen. This made me curious, wanting to taste it because it’s so rare to have my feelings changed so fast from nightmare to first love.





This diagram show different parts of our tongue is responsible for different basic taste. To be honest, when I was tasting the chocolates I feel that every part of my tongue seems to taste the various tastes. Hence, I researched and discovered the tongue map is a myth. The research of Edwin Boring and Virginia Collings revealed that all tastes can be detected anywhere there are taste receptors which is all around our tongue. Only that the degree of sensitivity varies at some areas of our tongues leading scientists to assumed areas with low sensitivity were areas of no sensitivity.

Tongue Myth Debunked

Does our nose works the same way as the tongue?

Air travels pass the millions of olfactory receptors on the roof of nasal cavity. Odor molecules stimulate the receptors that sent signal through the olfactory nerve to the bulb. Signal from the bulb spark memory in the brain. 80% of the flavors we tasted come from what we smell. That’s a lot from our nose.

Fun fact: Humans can recognize 10000 different odors but no two people sense the same things.

21 Smells 90’s Girls Will Never Forget

I saw this article on BuzzFeed. This seem to be an interesting topic to work with in Singapore Context like toys we play at Mama shop when we were young. That will be so nostalgic and fun to go back to those days.



A unique tear drop exhibition on smell and memory but i think its hard to pull off. Each person has their individual interpretation on a same object like wood smell can be interpreted as burnt wood, wood after a raining day, etc. I think they probably get the most distinct smell that everyone can recognize to evoke the memory of the place or object.

Tear Drop Exhibition



A creative installation that explore Singapore through scent. I wonder how Yishun smell like? Will there even be a distinct smell that make me recognize it?

Scent Map Singapore


Make your own Smell memory amulet! It records smell like camera. So advanced and simple to create. I want a floral light refreshing scent to calm my nerves at all times.

Smell Amulet Kit


As I was researching, I reminded of the Poke-Senses box game I created for my portfolio to enter ADM. The rules are simple. There are nine holes containing different things to feel. Some are nasty and some feel good. Basically, poke your finger into the hole at the start line and try to navigate your way out. At the end, there will be two path; one good and another will chopped off your finger just kidding but it will hurt.
