The Spinning Girl

OK, check out this image.



Is she spinning clockwise, counter-clockwise, or both? Answers below the jump.

I see her as only spinning clockwise. The hubby sees here spinning in either direction; it changes if something causes the screen to change. I also found that if I look at the shadow rather than the girl, I see her spinning only counter-clockwise. Weird. For more info, check out this post at Neuroligca Blog. Enjoy!
