Build an Android Head

Here are instructions showing you how to build a robotic android head for under $600. Using a computer, you will be able to control the head's movements, and look through it's video camera eyes. Kinda reminds me of the scene from Alien when they reconnect Ash's (the android) head to get information from him about the Alien. There was also the Star Trek episode where Data's body was destroyed, and Riker had to connect Data's severed head to the computer. Any other geeky talking android head references I missed
