LEFT BRAIN v. RIGHT BRAIN

Is the woman spinning clockwise or counterclockwise?

[Note that she spins much smoother on the article site than she does here, so you might want to go check out the article before making a decision on direction.]

According to this article, the way you see it spin tells you which side of your brain is dominant. If you try to engage the opposite side of your brain while not looking at the picture, you can make her switch directions.

I initially saw her spinning clockwise, but was able to make her switch, although I don't know exactly how. Are you right brained or left brained?
