It’s 100 year old technology called a lenticular film that’s bonded to a high resolution display.

Making a lenticular film that small is tough but not rocket science. The software is doing most of the magic interlacing the images properly.

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).

It’s not rocket science, it’s laser science.
