Iris Tubes
This program draws an endless series of unique, random pictures of an imaginary eye. No eye pattern will ever appear again!
Each eye takes a while to build up, so let it run for a while to build up the textured pattern. If you’d like to start a new eye, just click anywhere in the image. Note that the speed of the program depends on your computer and what else it’s doing at the moment!
