Another geeky mario brothers related thing here... some of you may already have seen this video, but this kid is incredible. He plays through a whole bunch of songs from the Mario Brothers series of games on piano, all from memory, blindfolded for the first song or two. It's crazy, and gets especially amazing at the end if you watch through all 10 minutes of it.
