This is a really neat bit of inverted thinking.
A Nintendo Wii Remote can be used with an ordinary PC. It tracks its position in space relative to fixed infra-red light sources. It can work just as well if the sensor is static and the light sources move. Johnny Chung Lee demonstrates how a fixed Wiimote can track up to four points simultaneously, adding multitouch or head-tracking capabilities cheaply to any PC display.
