Best Optical Illusions

There's a contest for the best optical illusions of the year.

Below is first place. Second place (on the page linked above) is also awesome.

The dots keep changing color continuously, but when they move you focus on movement and not color change. It's unlikely that a lion trying to eat you is going to change color, so it's good we evolved this way, but interesting nonetheless.
