EyeToy: Play (PlayStation 2)

Sony's EyeToy is a small digital camera that sits on top of your TV and plugs into your PS2. The motion sensitive camera films you as you stand in front of your TV, putting your image on screen in the middle of the action. Then you use your arms, legs, head, bottom... in fact any part of your body to play the games. EyeToy is an entirely unique party gaming experience for people of all ages. Incorporating a unique USB camera that utilizes motion-tracking technology, gamers instantly become the main character in their own game as interactive entertainment is taken to a new level. Features 12 mini-games that let you beat back ninjas in Kung Foo, perform rhythmical feet tapping in Beat Freak, and show your leg work in Soccer Craze.
