Here it is - My rendition of a 2-axis light follower. I went ahead and clipped the IR Cam from the wiimote to cut down on weight.

A serial port is used to connect the box to the microcontroller.
Here are some Pictures:

Would you like me to build you a project box with a lovely Wiimote Camera? Let's talk!
