Play with your iSight
by Volker Weber
Now, you just have to make sure, you don't fall over:
Toysight is set of cool games and toys to play using your iSight or similar firewire camera. Using a system of object and motion detection to track your position, Toysight allows you to control buttons, sliders and perform gestures on the screen, putting you right in the action!
