Flip Books (question mark?)

So I was thinking about what some different kinds of interactive media could be. I went to wikipedia to see what other people have said about interactive media, and in the terminology section, I noticed one example of interactive media is flip books. I never thought about how you have to interact with flip books. In order to experience the art in the flip book, you have to flip the book - creating interactivity. I don't know about anyone else, but I used to make flip books all the time in school when I was bored. I always made the classic stick figure who would run up a hill and then fall off the side of a cliff where he would fall for a few frames before he slammed into the ground and his stick figure body parts went flying all over the post-it-note page. Check out this one below. Reminds me of a young director I used to know (myself).
