From Gerb Sterrenburg comes a followup on a previous experiment, and this time it’s even more mind-blowing as no special hardware is needed, you really have to see the video to see the awesomeness of the work that Gerb, along with StrafWerk did.
So be sure to check the video on his blog: http://www.gerbster.nl/2009/04/07/head-tracking-in-flash/
Michael please drop me an e-mail, I have a project that I may need your help with.
