Check out the dancing lady graphic at this article.
Do you see her turning clockwise or counter clockwise?
I saw her turing clockwise and couldn’t for the life of me figure out how to see her turning other wise. Then I stared at her feet & their shadows for a minute or two and I was able to see it… Now I see both and she keeps changing direction every few seconds and it’s driving me insane.
I figure that since I saw her turning clockwise first and so easily that I’m a right brain thinker… Although I’ve always assumed as much. I’m more creative and imagination based than logic based. Your logic has no place here. 
hehe.
I can only see her turning clockwise, and I can’t see her going the other way no matter how long I look. Which makes no sense as I’m more logical than creative….
