Everyones heard of the WiiMote, but I've taken the next step with my Parallax Propeller interface for the C64 and added an Accelerometer. I've attached the Accelerometer to the end of a $2.00 wiffle bat, and programmed the Propeller to trigger the fire button of the 64 based on the G-Force reading. (See the monitor on the top of the TV in the video where I'm monitoring the Accelerometer input.)
My son and I are playing "Street Sports Baseball" a great game for the Commodore 64.
