Which way do you see the dancer spin?  If you see her spin clockwise you are right brain which means that you are well let me say it this “artistic”.  If you see her spin counter clockwise you are a more logical detail oriented person.

Me?  Well I see her spin clockwise.  So much so that I can’t see it spin the other way.  I guess that is good for photography.
