Oh, that's how it works.

So, I looked up how the 3DS works: Parallax Barrier. That's pretty neat. I hadn't heard of that before but lenticular is more familiar and I had wondered if it was something along similar lines. I also did notice in the store that the viewing angle was pretty narrow.

(I tend to be a late adopter, tho, so it's likely to be a long time before I get one.)
