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.
