Remember Johnny Chung Lee's self-made VR head-tracking system cobbled together from a Wiimote and IR-equipped safety glasses? Good, because it's now one step closer to its destiny as the ultimate controller for a first person, Wii shooter. The video experience in a 3D wireframed world does look admittedly rough, but the idea is sound: step forward to move forward, to the sides to turn, and jump to (you guessed it) jump. Fortunately, with Nintendo's WiiWare service now live in Japan, maybe, just maybe someone will see the potential and commercialize this. Watch the Insight VR people hunt down the evil Marshies after the break.
