An animation of what? It would be much more difficult and take way more space for a flip book, and it doesn't contain much more information than a few pictures, let alone a book full of pictures.
I was thinking an actual film, which wouldn't be difficult.
I kept thinking about the "how to tell future people about radioactivity" example and I think it's hard to convey the actual effects, while it may be easy enough to convey that it's dangerous.
A movie would be much more apt at explaining what was there and what the consequences of irradiation are that a few stills.
