Left or right?

Look at the below image for a minute or 2.
Is she turning clockwise or anticlockwise?

For me, at first glance it was clockwise, then after a minute or more, it began to turn anticlockwise. Then after a moment it's back to clockwise again. Woah, I thought my eyes were playing tricks on me. But after a period of time, it seems to set turning in the same clockwise direction. But if I were to try concentrate really really really hard I think I can try make it turn anticlockwise. Weird.

Well... An ex-colleague shared this test with me. However the test result is in portuguese. He said he only sees it turning clockwise-anticolckwise-clockwise and had been clockwise ever since, whereas his girlfriend sees it turning antoclockwise only. I tested this out on 2 other colleagues. Both have different results. One sees it turning clockwise only and the other anticlockwise only. Guess it's cool for one to be able to see it turn for both directions.

So what direction is it for you? Post it in my comments! I would love to know.

- TEST RESULT -

PORTUGUESE VERSION
"Supostamente, se você estiver estimulando mais o lado racional do cérebro (o esquerdo) você verá a mulher girando no sentido anti-horário. Caso esteja utilizando mais o lado direito do cérebro, ligado a subjetividade, ela gira no sentido horário."

TRANSLATED VERSION (from dictionary.com)
Supposedly, if you will be stimulating more the rational side of the brain (the left) you you will see the woman turning in the counter-clockwise direction. In case that it is using more the right side of the brain, on the subjectivity, it turns in the clockwise one.

MY TRANLATION FROM ABOVE
Suppose if you see the woman turning anti-clockwise, it stimulates your rational side of the brain (left brain). And if you see it turning clockwise, for most people would, you are using more of the right side of the brain.

Test your brain and see how much of a left or right side person are you. For me I'm very balanced, 46% left, 46% right - perhaps that's why I always have the problem of contradicting myself.
