My version of this involved a Wii remote: freshmen-level CompSci class, and the group had to build a simple game in Python to be displayed at a showcase among the class. We wrote a space invaders clone. I found a Bluetooth driver that allowed your Wiimote to connect to your Mac as a game controller, so I set up a basic left/right tilt control using a Wiimote for our space invaders clone.
The Wiimote connection was the star of the show by a long shot :P
