Spying eye robot

This is my creation of the spying eye robot, created by Bart Venneker.
Video can be found here (in Dutch):

You can find the code for arduino and the necessary python script on his website: http://www.bartvenneker.nl/Arduino/index.php?art=0031
As well as the schematic and the components used

What it does:
You place the robot on top of your screen,
and when the mouse pointer moves, the robot's eyes will follow the mouse pointer.
