I saw a demo of active LCD shutter glasses triggered by an IR transmitter on an SGI machine in 1992 (and it was mind-blowing)... This is not new... not even close... I saw a prototype of glasses-less 3D TV at the MIT media lab in 2003... (admittedly using an obscenely large heavy active lens in front of the tube)...
People seem to be talking about this stuff as if it was new. It is just gaining commercial momentum because other display technologies have stalled (OLED), and LCD technology has finally started approaching the contrast and refresh rates that CRTs had 18 years ago.
Mind you, I'm thrilled to replace my 23" SGI CRT with a Samsung LCD weighing less than 1/10th as much with a nice sharp digital image, but since color and viewing angles are important to me I have PVA panels, which are still limited to about an 8ms refresh rate. My SGI could do 1920x1200 @ 140Hz
Grump grump...
