Lol today I tried sticking 3 normal leds on my headset and with the program ULF recomended I tried to get some results. Well, it works pretty good (especialy in a dark room) didn't see real 3D yet but I guess that ULFs program doesn't do the right calculation for that. Only got x, y and z movement to work, and panning my head. Pan and tilt at the same time caused severe movement problems . Anyhow, I might go on with this and try calculating and programming from scratch, but sadly I have almost no experience with webcam, rotations ánd perspective calculations. This could take a long while .

Sorry for the very vague and blurry images, but I don't have enough light at the moment:

1: 2 1.5V batteries and the red upper LED
2: Green led at headphone side
3: The result, 3 LEDs parallel solded to 3V.

Not to be arrogant but seen that this is my first project ever where I touched a soldering iron, im pretty proud on figuring everything out myself . (Only took me 2 hours to realize I didn't need any resistors with 3V :|).
