Arduino Light Dependant Resistor

The image above shows a Light Dependant Resistor. It functions very simply. I used it with the Arduino to measure the ammount of light in my room. I didn't know until today that I had so many spare components lying around. I'm interested in the things a LDR can do, I think I'll try to create the robot featured on this website. Now all I need is to find an inexpensive servo. :]
