I posted this years ago, and I still find it fascinating.

 Which way is she spinning? Can you make her change directions?

The Right Brain vs Left Brain test … do you see the dancer turning clockwise or counter-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 counter-clockwise though you can try to focus and change the direction; see if you can do it.

Of course, my brain is different. She’s spinning clockwise. And I can make her change directions at will.
