These are probably the best optical illusions I have ever seen. Each one of them blew my friggin' mind when I first saw them.
This one prompted me to e-mail the creator and give him a "nicely done" email. He replied and said thanks :) He is a professor at MIT and seems like a nice guy.

This one is along the same lines as the above. The central section of the intersecting crosses are the exact same colour.

Stare at the centre cross for a moment, and the moving dot will eventually turn green. Stare at it for a moment longer, and all of the dots will disappear except for the moving green dot.
