The eyetoy is definently worth buying fro 2 reasons.
1.) some of the games can be "fun" for a few of the boring minutes of your life and i do not support anti grav at all. that game sucked @$$!
2.)If you google something like eyetoy as webcam or something like that you can download a driver and use it as a cheap video camera. you plug into a usb port. it even has a small microphone in it suprising ly enough.
