Have a webcam? Like Wii technology? Dont have $250 -- Check this out!

"It's a Wii without the $250 console. It's virtual Pong and so much more. Any object is now an input device, even your fingers. Camspace is a pure software solution that allows nearly any ordinary PC webcam (95% are supported) to track up to four objects - even as small as 5mm - in real-time and with very high accuracy and reliability (Windows only). Techcrunch has an in-depth article and a video."

Very neat idea, but it appears that it is in a limited beta only, and source doesn't appear likely.
