Found something interesting for Wii owners. Apparently people have "hacked" the wiimote to use it as a PC input device as well as invented software that allows it to be used as a virtual set of drumsticks.. It is still buggy and imo will never replace real drumming, but it's certainly an alternative to key and mouse input for programming.
