The Sixth Sense Device ... !!!!!

I just landed up on this site a couple of months ago, and realized it's sheer awesome-ness. However, this one video I saw today has topped it all in terms of every damn thing that I could imagine of. Pattie Maes, a professor at MIT's Media Arts and Sciences programme displays one of her Lab's projects (The Media Lab at MIT) -- a device she calls the 'Sixth Sense Device', engineered by a student of her's, Pranav Mistry. Have a look at this video, and you tell me if you are not bowled over completely too !!!
