I finally got a good LED strip to place behind the cameras, 300ma at 3.5volts. Makes a lot of difference in the calibration.
I am just playing with simple-solutions to 3D right now. It really is intriguing trying to figure out a non-moving picture way of getting 3D distances. It is really easy with a single item like a pencil on a plain background. But that's cheating. My attempt at subracting the left and right eye, then showing only the pixels with the same +/-3 of 16 brightness values... basically failed because it produced no useful information.
