Subject: [TECH]    What do you think of this 3D technique ?

The company is Canesta.

They use time of flight of light to measure distances on a pixel by  
pixel basis.
They drive an LED with a square wave waveform at 44 MHz.  Then they  
measure the inphase and out of phase light incident on two pixel  
arrays that are driven by the same waveform with phase offsets.

It looks pretty cool since the computations required are much reduced.
