I have used one at the University of Michigan, and I have one at our offices as well. In fact, they are so easy to make (if you have the money) that DIY instructions are available at http://geowall.geo.lsa.umich.edu/intro.html - all you need are two DLP projectors, two polarizing filters, a projection surface which preserves polarization (or ours which preserves and rotates 90 degrees) and cheap e-bay polarized-per-eye glasses. When we put ours together at the office, the biggest problem we had was getting a polarization-preserving projection screen. I guess I just wanted credit to go to the people who pioneered this stuff, the geowall folks. Now, we have only been using it with geomatics imagery and doing stereo video the way they are doing it may be novel - but I bet someone familiar with stereovideography would claim old hat. Give the geowall people a hand, they worked HARD to make this happen. p.s. our Geowall cost us $3,900(CAD) to make. Well within reason for a dedicated hobbyist.
