Wow.. that is uber geeky and uber cool...

Great potential for games there... and with technology already available.

It's getting there.

I've been speaking to people who work on developing stuff for the PS3, and soon, you won't need any kind of remote or glasses or other transmitter! All you'll need will be a usb webcam and face recognition. You're already getting this in cameras and stuff. Soon they'll be incorporating that technology so as long as you don't turn your head away to one side, it will track your face and render graphics 3Dmensionally

Looks promising
