NuVision 3D LCD shutter glasses
I've Flickr'd before about NuVision's glasses from our trip to the JPL open house in May (here). Basically, each lens is a solid LCD pixel that can turn black to shut off that eye, and by making both turn alternately on and off, faster than you can detect, each eye will see every other frame of video on a screen, and if every other frame of video is from the opposite eye, then you see 3D. In practice, I can see the flickering of the LCDs turning on and off, but only if I'm not lost in whatever I'm looking at. The wireless glasses are battery operated by flat watch batteries, and they sync up via the little IR-detector holes right above the nose, which watch an emitter hooked to the display device. These are a slightly different style than the ones in the JPL gallery. New model maybe.
