Spinning dance optical illusion OCT 11 2007
I've been obsessing over this optical illusion ever since I ran across it yesterday.
Is she spinning clockwise or counterclockwise? Or both...and how is that even possible? It's a left-brain vs. right-brain test...which way she spins for you determines which side of your brain is more dominant. (Tip: if you're having trouble getting her to switch directions, focus on a point a couple of inches below her feet...that seems to do it for me.)
