I've made a wireless controller driven by movement, with support so plugin pedals and a software to emulate a normal Joystick in order to make it usable in any Windows software, game or simulator. The chip was programmed by an Arduino board.
It's pretty cool. See the video below: http://www.youtube.com/watch?v=MMsvuwvJqlE
