Head Tracking

Originally Wiitrack. Changed to Head Tracking after webcam functionality was added.

The Head Tracking plugin allows you to use a webcam or a Wiimote to track the location of your face relative to your screen and use that information to distort Compiz's OpenGL projection to give your desktop a real 3d feel. Head Tracking also adds real 3d depth to your windows based on their stacking order to make the effect more noticeable.

If you plan on using a Wii Remote with infrared lights to track the location of your head, you will need to use the Wiimote plugin.
