Flipbook... =)

The flip book first appeared in 1869, patented by John Barnes Linnett. Although at that time it was called the kineograph. It was the first form of animation to employ a linear sequence of images rather than a circular.

Flip books, like motion pictures, rely on the persistence of vision in order to create the illusion of movement rather than the user seeing only a series of images one after another. In order for the book to work, it must be flipped through with enough speed so that the images do not just blur or appear as still images.

A flip book is a book with a series of pictures, varying gradually from one page to the next.  When the pages are turned rapidly, or flipped through, this causes the pictures to appear as one moving image. Flip books often appear as an added feature in the corner of a childs book or a magazine, and are not generally sold as a seperate book.
