This is a really great idea. Better than the LCD shutter glasses i still have lying around in a box somewhere since you dont need a 200Mhz screen display to get a 100Mhz 3D picture. Also, These shutter glasses work with every OpenGL / DirectX compatible game just through an additional tool which reconfigures the nVidia driver for the 3D display and i think it should be fairly easy for nVidia to adapt that tool for this 'reverse wii-mote' method. I really would like to see this concept turned into a real world product and if the hardware is solid i'd be really happy to shell out a 100 bucks for this.
