Since everybody is so captivated by this [not!], I'm going to just come 
out with it now.

You remember the chaos pendulum? A metal weight suspended over three 
magnets. A while back I make a simulation of its path.

Well, this is 102,400 chaos pendulums, all running in parallel, but each 
one started from a different initial pixel location. And each pixel is 
coloured according to how close its pendulum currently is to each of the 
three magnets. (The magnets are red, green and blue.) If you watch the 
animation, it appears to "pulsate" due to the typical swing period of 
the pendulum.

In this simulation, there is no gravity, no dissapation, and the magnets 
produce linear forces. I plan to try quadratic forces next, and maybe 
add some gravity. I'm expecting to find quadratic force makes the 
patterns a lot more complex...

BTW, I have done animations with other colourings. Best of all was a 
sky-like agate pattern that morphs to the swing. But it keeps crashing 
POV-Ray. :'{
