"Wiggle Pictures"- real name?

Hey all. A friend of mine has an idea for an album cover for her CD. She wanted something with pull-out tabs like you find in children’s pop-up books, but I think the idea would work better with a “wiggle picture,” which is the only thing I’ve ever heard it called. I’ve seen them mostly as special baseball cards- they feel ribbed to the touch, and you see a different image depending on which angle you view them at.

Anyone know what the real name is (and, I suppose, how one would go about producing them)? My Google-fu seems to be weak this weekend.
