Optical Illusion?

[Lemur]

I need help. This is driving me nuts. In theory, the picture below is an optical illusion, and most people should see it rotating counter-clockwise. It's something to do with left-brain right-brain dominance. I can't see it. I look at it with one eye, then the other. I look with my peripheral vision. Nothing helps. It's going clockwise. It is! I cannot, for the life of me, look at it in a way that reverse the direction.

Help me, fellow Orgahs. Look at the image. Which way do you see it rotating? Is this a legitimate illusion, or a malformed GIF? Does anybody see it rotating counter-clockwise?

[GeneralHankerchief]

I can see her going both ways with a subtle switch in vision. Don't worry Lemur.

[FactionHeir]

CW only for me, same as Lemur.

[Samurai Waki]

I can see it going just CW

[Warmaster Horus]

Erm, that's definitely clockwise for me; but my parents said they could see it counter-clockwise briefly.

[Samurai Waki]

Aha! I got it. You have to very closely Concentrate on the foot. And I mean close... like my eyes were practically touching my computer screen, and as soon as I noticed the change backed my head away, and now it won't change back to CW!

[shlin28]

Hehe... now I can change the direction at will.

Blinking helps

[shlin28]

It works for me, try to focus on the foot, then it somehow changes

[CountArach]

Nope, can't see it.

And no babes outside the babe thread

I first saw it as CW. If I look at the more "outstretched" hand when it appears to be crossing the sillouhette in the "back" and imagine it instead to be crossing in the front (or vice-versa) I can switch most easily.

The CW one looks more like your looking slightly down on her, whereas the CCW one looks like your looking up at her somewhat... maybe why the CW is the first one that tends to be seen.

I, for one, can move it in either direction at will.

Looking at just the shade helps, then you can 'switch' the direction. It's funny, I just knew it was about this illusion when I read the title. I spend half an evening looking at it last week. It took me an hour before I could change the direction. But I still can't for the life of me figure out how this illusion works.

Holly mule! I could swear she was absolutely whirling counter-clock-wise and when I scrolled down a few millimetres to post the reply it turned clock-wise. Now I can't see the other way.

And now she's again rotating counter-clock-wise.

I can only see counter-clockwise rotation. Must be because I can't unwind this evening.

[Ice]

It was counter clockwise first.

I then took advice and stared at the woman's foot and now it is clockwise.

[Hepcat]

I can change it's direction just by concentrating on it. At first it was just counter-clockwise, then I just had to think about it and it changed and now I can change it's direction quite easily.

[UltraWar]

I can control both directions.
