Thanks for all the updates, BHawthorne. I recently started investigating nvidia 3D vision, surround setups, etc. I have a decent budget and would love to set up a multi-projector rig and do some testing of my own. Only problem for me though is I live in the city in a small apartment, so I only have about 11 x 11 feet of space, and I can't alter my place. And, I'm not too great at woodworking and no access to a garage / tools etc. But what I'd do for a even a 150 degree circular screen My current setup is a 100" screen and single projector.
