Roomball (Score 5, Funny)

A friend just gave me her old Roomba to hack, so this is great timing! I'm going to use it to realize an idea (dunno if it's original or not) wherein the hacked Roomba lets me turn any room into a gigantic pinball machine. It'll have more bump sensors, a frantic motion algo, a crap-load of blinky lights and sound-effects, plus a digital display (in big red numbers) that keeps score. You set it down, aim it into the room, and let it go. A timer stops it after X minutes. High score wins (or whatever). I'm gunna call it "Roomball" . . . or maybe "Pinba". My cat will never forgive me.
