Anyone checked out Freetrack yet? http://www.free-track.org/ Came across this little gem a few days ago and doesnt appear to have been mentioned here yet. Basically its a freeware competitor to TrackIR, which is software/hardware that tracks movement of your head so you can control camera angles in racing games/flight sims etc, works with rFactor, GPL GTR2, FLight Sim X etc. Software is free and there's instructions to make the LED hardware at the site. You just need some basic tools, LEDs and a webcam to bring it all to life. Nice little youtube clip of it in action below with one of my favourite games, Future Pinball (works with that too obviously). http://www.youtube.com/watch?v=oJHAdXT7-tc Do a youtube search for Freetrack and you will get plenty of examples of what this baby can do. Enjoy.... and give some feedback if you decide to make one.
