Left-Brain vs Right-Brain

Go here [Link] and see which way the dancer is rotating. Clockwise or counter clockwise? Can you make it change directions. I can, but I have to concentrate for a few seconds. Really neat.

The Right Brain vs Left Brain test ... do you see the dancer turning clockwise or anti-clockwise?

If clockwise, then you use more of the right side of the brain and vice versa.

Most of us would see the dancer turning anti-clockwise though you can try to focus and change the direction; see if you can do it.
