Optical illusions- Who is this guy and why does he have such staing power?

Make this image big, (ie. click on it). Focus on the the four little black dots in the center for 30-40 seconds. Look at a flat colour wall for a few seconds. Blink your eyes a couple of time.
I have no idea how or why this works. This guy must be magical!
