I got Guitar Hero III for Christmas from my inlaws and every time I play I have maxed out at 1 hour because of the arthritis in my left hand. I saw this video on BoingBoing today:This guy ripped apart his controller and built a turntable controller. At minimum I am going to see if I can use the guitar like a lap-steel - Star Power could be interesting.
