[.041 Safety Wire]

If you have the least little bit of technical savy you can put a 2dof setup together for practically nothing, 5 0r 6 dollars for a kids nightlight, webcam and the freetrack software. swap out visible light led for an ir led and that is all there is to it. I mounted my vx-3000 webcam on my headset and the nightlight just above my monitor.
