I found this looking for optical illusions. The first link takes you to a page full of moving illusions. The spinning girl is a hard one to visualize. (she has eye controls to help) And the table illusion will have you marking a piece of paper and holding it up to the screen so you can measure the two tables.
The second link takes you to the main page of the site. Under the 'content' section there are more detailed visual tests.

I love optical illusions! Thanks for these sites.
The spinning girl was the wierdest one for me. She looked like she is spinning clockwise to me. But if you illuminate her eyes for counterclockwise it's obvious that's the way she's spinning. Then turn the eyes off and she slowly spins down and starts spinning the other way.
