what is a lenticular puzzle?

Lenticular is a word that describes the shape of a double-convex lens. A lenticular puzzle is a puzzle that takes advantage of this type of lens to create an illusion. The illusion works by showing you a different image depending on the angle at which you view the image on the puzzle. The image may show depth, or a completely different image as you change your viewing angle.
