OpenCV is a library originally developed by Intel, which is now free for use under the open source BSD license. OpenCV recently got some great exposure with this cool new video put together by developer Matt Ditton, who created a 3D version of pong in which your head becomes a paddle. The game make use of facetracking as an input device, similar to how Microsoft’s Project Natal camera or the PlayStation Eye might track motion of parts of a body. Check out the video below (thanks to Creativity-Online for the tip).
