Sure, Project Natal
is the hotness and a little bird tells us PlayStation Move
is pretty bodacious, but you don't have to buy a fancy game console to sooth your motion-tracking blues. When students at Cornell University wanted to play Human Tetris (and ace a final project to boot), they taught a 20Mhz, 8-bit microcontroller how to follow their moves. Combined with an NTSC camera, the resulting system can display a 39 x 60 pixel space at 24 frames per second, apparently enough to slot your body into some grooves -- and as you'll see in videos after the break, it plays a mean game of Breakout, too.
