jit.hue + random
This would apply the a layer of colour and when random are added it become ever changing effect.
I also play around with the rotation of output. Initially I wanted to achieve every 3 secs it will bang and rotation will appear however, I manage to make it with the ggate. Where I can control which side to bang. I also trying to increase the amount of pixel, but I did not mange to do, will try again next time.
