I think lobawad's challenge is a bit disingenuous, but works as a kind of object-lesson. I've always really liked that animation, but I don't know exactly why. I like the colours and the sinusoidal repetition, but I'm not about to hypnotise myself with it.
It's a two-dimensional simulation of, among other things, the way opaque solid objects eclipse each other in three dimensions, but it depends on that (and a specified angle to the illumination of the objects) to look cool. Basic facts for draughtsmen.
