Wow, that's cool
I saw anti-clockwise when I first looked. I stared at it long and hard and couldn't see it any other way.
Then I started reading the text next to it, out of the corner of my eye, it was going clockwise. For a while there I was convinced that the image actually changed direction. But then it changed back to anti-clockwise while I was trying to figure it out.
First she was pivoting on her right leg, then on her left. I couldn't figure out how that happened at first. Then I realized that the brain can't tell when the figure is facing you our facing away from you, and that's why it appears to change direction.
It's a very cool illusion.
