A CHIP is being constructed by using two brushes that are painting on the board through deterministic noise, and then turned squared and pixelated and blended into each other, with colours selected from 21 different colour schemes. How many iterations, and the speed and size of the added parts determines the final composition.
You can stop the iterations by pressing S, and download the current composition by hitting D, and restart/reload the iterations by pressing R.
Notes The thumbnail generation takes a while and the render/iterations in non-GPU browser can be quite slow. Chrome/Firefox recommended.
