It's a great alternative to those who don't want to spend a bunch on TrackIR or want to try out the whole headtracking thing before purchasing hardware.

FaceTrackNoIR is freeware, requires only a webcam (PS3 Eye for best results), and a human(?) face.

Works great and smoothly once you dial your settings in.

I thought I might chip in here as well.
FaceTrackNoIR is fantastic. I love the fact I don't have to wear anything to make it work either. (Yes, it works when you're naked )

As the above-mentioned post states, once you set it up correctly it's wonderfully smooth, and it just adds so much to the immersion factor.

And, it will only get better.
