This image of a dancer in a perpetual spin can be interpreted two different ways - she can either be spinning in a clockwise direction, or in a counter-clockwise direction (imagine her spinning on a clock face). Some people's perception may favor one direction over the other, and some people may see her change directions from time to time. The fact is that the image is a constant 34-frame loop representing 1 full revolution of the dancer, and no trickery is used to make her seem to be spinning one way or the other at any point in time. The effect is entirely caused by the perception of the viewer as he or she interprets the ambiguous frames where the spinning dancer's body appendages (legs and arms) cross over each other.

this is really interesting, at first i saw the black girl spin clock-wise and the next few seconds, she was spinning the other way around, counter clock-wise...^^
