Thank you, everyone, who sent me links to various shadow animations! I have had a lot of fun with them, and I shared them with the education office of the Harvard Museums of Science and Culture. For their immediate needs, they rigged up something with a flashlight and a dinosaur figure. It is not so precise, but makes the simple point to kids.

Does anyone have one to recommend that could be used with a museum video. Credit will, of course, be given. Thank you! Sara Sara J.
