What's the proper name for that kind of image-switching material that switches between two pictures as you tilt it? I mostly associate it with novelty baseball cards, toys, children's books, and so forth. That plastic-y corrugated stuff? If I wanted to order a bunch of postcards printed with it, what am I looking for?
