I saw this on the internet, and wonder if anyone here has tried it??? It looks like a freeware version that uses the webcam on your computer to track your head movements, much the same that TRACK IR does.

If all that I need is a baseball cap and 3 red LEDs, then I might just give this a try? Not much to lose and it either works or it doesn't!!! Place your bets now......
Anyone else using it already???
smooth landings.
