Interesting-looking free program that uses your webcam to track any object as a rotational and translational game controller. I haven’t tried it yet, but I can’t wait to play Tetris with my shoe.

CamSpace is a program that allows the user to control his favorite games and applications with any webcam. Use your body and arbitrary objects to replace the mouse, keyboard and joystick! Currently, CamSpace only works for Windows, but Mac and Linux versions are on the way…
