I've read Instructables and such for modding it with potentiometers to give control feedback on the movement, hooking it up to an Arduino for control, things like that. I haven't personally seen a version of this for the Pi, but the interesting part is getting it talking to a CPU controller at all, and it ought to be a pretty short leap from an Arduino to a Pi.

It's definitely not plug and play if you want to do anything interesting with it, though.
