A friend at work pointed me to Ken Perlin’s homepage, and my goodness, what a lot of cool stuff he has on his site. Professor Perlin is a very busy man. There are a bunch of nifty applets to play with, but one I spent a while messing around with was the highly addictive ladybug game. The path planner applet is also nice, and looks like the it might make the basis for a future MATLAB programming contest.
I never did manage to win that ladybug game.
