How to Stop Time

I found this groovy little illusion: How to Stop Time. It involves looking at a the second hand of a clock out of the corner of your eye, and it appears to stop moving.

The site gets cheesiness points for trying to convince people that they are actually stopping time. I do wonder what the actual explanation is, though. I've read about people with brain damage who are blind to movement: when pouring liquid out of a glass, they see it frozen in mid-pour, then the glass is suddenly empty. Perhaps this illusion is related to that, allowing normal people to experience change blindness without ramming a pole through their brain.
