I believe the image is a parallax barrier type 3D image.

This display premiered at last year's Stereoscopic Displays and Applications
conference.  You can see a picture of it at:

It's the eighth set of images down the page.

The display makes use of the "3D Black Screen" material developed at QD
which allows polarised 3D rear projection to work extremely well.  
In the box I believe are two video projectors (one for each eye) - each
with a circular polariser in front.

A larger version of this was used as the main 3D display for the 1997
conference - this used two 3 gun CRT projectors.  Impressive stuff.
