Poor Man's Stereoscopic Projection

Jed Link writes: "This summer I helped built a Geowall stereoscopic projection (3D) system for the Southern California Earthquake Center. Although there are no new concepts involved with this system, what is new is that the system cost a little over $10K and is comprised of materials that you can buy at any computer-hardware store. A complete description of the system, as well as a diary of its assembly is available here. Traditional stereoscopic projection systems like The Cave which is used primarily for new product modeling and on a few university campuses cost anywhere from $150K to $1.5M. They are built into a fixed location, often requiring significant architectural modifications, so transportability isn't even an option. The Geowall, on the other hand, can be fixed to a cart (like we've done) and rolled from room to room. The price-tag makes the system feasible for undergraduate post-secondary education classrooms and even high schools. The system is based on a very simple concept, and while its use is currently primarily educational, I think it's only a matter of time before we see something like this in the gaming or entertainment industries."
