Optic effects
I found this through
xparrot.
It's a fascinating optic effect (illusion).
The Dancer
I have no idea if this really can prove if you are a left or right brainer. However, at first, I saw the woman turning anti-clockwise, then I got her to switch, and she turned clockwise for a while. Now, I found out that I can make her switch deliberately by following the leg to the shadow. So, I always see her turning anti-clockwise, and I have to concentrate a bit if I want her to change directions.
Eyes and brains are funny things.
Edited: for clarification and wording
