After watching the movie, "21" I wished I was a student at MIT doing something totally awesome. Today I became a little bit more jealous, I know it's early but all I want for Christmas is an MIT brain. :)
Warning: The pure geekiness of this new invention may cause your jaw to drop, permanently.
The MIT Media Lab created an invention called, "Sixth Sense." Describing this device isn't going to do it justice, so here is a video. Once it has a sleeker more attractive design, this could be a daily accessory. (Man, I feel geeky for posting this one)
