So over the xmas period I messed about with an oldie, but so much fun to implement - Boids! It's more intensive that you might thing as each boid has to test itself against every other boid in the field, but the flocking behaviours are lovely to watch.

A small BASIC proggy I did in my spare time, for fun. It's a stereo pair, cross-eyes.

Oooh gotta test video with a stepping illusion!
