Ah, a different word than what I was going with :)

What word were you going with?

I think of lens-shaped objects, particularly lenticular clouds.

Until now I did not know what the name of those moving images were.

Ah, that's what I thought you meant too, but I'm a bit confused about what amazed you in the name. It's a good name, but I think it doesn't make much sense in this context, if it weren't for lenticular printing.
