Ryan writes in with an awesome Xbox hack! “An Xbox headtracker system – Built for around $6.00. I interfaced directly to a xbox controller pcb with photo resistors. Using some cardboard and tape and a led head mounted flashlight and some wire i made a useable headtracking system that is based on using the right thumbstick as an interface as it is usually for camera control in third person games, or direction in first person shooters.” Link.
