As we are doing rubber tree in a chronological order, I was thinking of showing timeline of what happen through the years in Singapore on the rubber industry. Below are some exhibition design that does on the theme of chronological order.
It is not new and many exhibition shows timeline of events and actions that happen. Significant events are important to take note and how it affect the later dates.
While it is not difficult to do, it may be time consuming to create a beautiful visual aesthetic timeline. 
Something simpler with black and white images might actually do the trick.
We might also have to think about the space and how we are able to print it and display it on the wall.
We need to discuss soon.
What a fantastic collection of visual timelines! Where are they from? Which one will your group go with and why?
They are from various galleries which I have no idea yet. I was thinking of the interactive but you said you don’t care about them, so we see where this will lead to.
