Right Brain, Left Brain?

Interesting post on Freakonomics today, a spinning dancer who apparently changes direction based on whether you are left- or right-brain oriented. Not sure if it actually has anything to do with dominant brain structures, but it is interesting that the motion can be interpreted different when, for me, the dancer is *clearly* moving clockwise. I'm going to try looking at it this afternoon after a couple of hours of painting to see if that changes anything...
