This is an interesting test to see whether you are more right brain dominant or left brain dominant. Which way does she spin for you? Clockwise means you use more of the right side of your brain.
I can only see her spinning clockwise, no matter how hard I try. For a brief moment I thought I saw counter clockwise, but it was just a split second and then it was gone.
*Update: After much staring, I finally see counter clockwise also. And I can switch back and forth between them!
