Ahh, 3D gaming. If you've been around computer games as long as I have - *cough*C64*cough* - you'll probably have had the same crappy experiences I've had. From huge headsets in malls for those first virtual reality games, to bizarre shutter-glasses for Sega's first console, to red and blue tinted glasses for dinosaur games on the Mac. All of them designed to give equal measures of unplayability and migraine.
Which is why this little video is so cool. A home brew 3D system (if you can call it that when it's done by a tech student at Carnegie Mellon), it uses a Wii sensor bar to track head movement, and generate a pseudo 3D environment that relies on perspective change rather than binocular vision.
Oh - hell, just watch the video. It's cool :)
