There's actually nothing about the picture itself that shows if it's going clockwise or counter-clockwise, it's just that our brain sees it one way or the other. I initially saw it as going counter, but now she's going clockwise all the time for me. Apparently it's possible to change the way you see her going by concentrating really hard, but I can't do it. =/
Oh, and the thing about using one side of your brain is complete bullshit. This has nothing to do with that stuff.
