Lego Mindstorms is a great peripheral (if you want call it that.) It is amazing what you can make with it: rovers, rope climbers, pinball machines and someone even made a scanner! Does anyone else have Mindstorms? (For Macs, you need Robolab)
I have it (with Robolab of course). I haven't used it in a while though, probably because it uses a serial port which my PowerBook doesn't have, and I'm too lazy to boot up the 8500.
