We've seen Wii remote-assisted Kinect FPS controls before, but how about completely controller-free? Now, thanks to one Bill Maxwell, the Kinect-powered, controller-less FPS is a reality -- and with one hand, no less! The claim that it's "better than a mouse" seems debatable, and we didn't notice any strafing (kind of important in FPS games) but it's still very impressive and handily proves the concept.
