While bored during the Super Bowl, my friend showed me a game he has for his GameCube. It is called Donkey Bongo. Instead of a joystick, it has a pair of bongos you hook up to the game system. Then it plays a song, and it can be any type of song, Tchaikovsky, doo-wop, B-52s, what have you. You have to play along and hit the bongos where noted and in the way it says. Right bongo, left bongo, both, do a roll... It even has a sound sensor because you are supposed to clap sometimes. Now this all sounds very easy, but it is actually quite difficult, and I have a good sense of rhythm.
Anyways, that's my recent bongo experience.
