Brian Dwyer built this nifty 2-axis light follower using the infrared camera from a Wiimote, a couple of servos, and an Arduino. It looks to be a proof of concept project so far, however I like where they are headed, and appreciate how the author was able to combine commodity hardware with a simple 8-bit microcontroller to do a fairly advanced task.
The source code is available here, and requires the Pixart/Wiimote sensor library by Stephen Hobley.
