2852 - Illusions

Here's a LINK to an optical illusion page. The trick is to slowly scroll down the page to see 6 illusions in motion. (Use the side bar to scroll.) I'm not sure what the first illusion is supposed to be.

#2 - pacman spitting balls into a gear

And then, there's more. This one is up Bilbo's alley. I challenge his dance group to do something similar.
