My senior year of high-school I made a similar display. I purchased a lenticular screen, coated it, and modified a projector to make a much smaller image than intended. Alignment was tough, but I ended up with about 4" of useful horizontal space with a fairly narrow viewing angle.

There really isn't any magic, it's just a lot of pixels to push. I was able to do a Utah Teapot to 2 views at 400x600 on a 100MHz 486 (it was an 800x600 projector).
