Larry Moran at Sandwalk posts a video that, he says, "does an excellent job of explaining the difference between science and superstition." While not exactly visually sophisticated, the video does include some good lines such as, "Facts aren't changed by our feelings about them" and "The person who declares evolution to be nonsense because no one's ever seen an ape mutate into a man is as conspicuously uninformed as the person who shouts 'Snap!' at a poker game, though of course their own lack of comprehension prevents them from seeing it."
If you've been in need of ammo for some of your "but evolution is just a theory!" friends, this video is for you.
