I finally finished the theater installation Saturday, and got around to viewing the stereograms William sent me just now. They look great, absolutely amazing projected to (on my screen) several feet by several feet. My screen is actually about 11' wide but that's for 16:9 video. These shots are much more rectangular but they fill the screen vertically.
I'm hooked. Got to buy that macro rail, but I also notice the moved people in a couple of shots and I think I'll really want a stereo camera too. But I can start with the rail as that is cheap and easy.
