lenticular

The 3DS screen is closer to one of those lenticular "3d" things you'd see on a ruler or a bookmark as a kid.

It's a good name, but I think it doesn't make much sense in this context, if it weren't for lenticular printing.

Explain what lenticular is on the home page, and maybe show a photo of an actual example?

This is just a more advanced version of the lenticular display on the Nintendo 3DS.

It is 3d, but it's like an improved lenticular process; it has many views, but they're discrete not continuous, and they don't float above the display.

Vertically-aligned is a good way to get 3D out of lenticular prints because each eye sees different images.

The displays are tricker, but possible, traditionally through the use of hexagonal lenticular lenslets carefully registered onto a 2d "flattened" projection of the light field capture.

That's why we're honestly so excited about using lenticular type technologies with gifs — they both feel like dumb, old technologies that are actually kind of wonderfully straightforward, and have a lot of creative potential!

"Also, the lenticular lens restricts the image to a particular viewing angle, not a particular height, so kids standing farther away will see the adults-only image, and adults standing very close will probably be able to see at least the upper portion of the kids-only image.
