I see it going clockwise - it's weird - I can see how one would see it going anticlockwise, but I can't see it going anticlockwise. :o

She started counter-clockwise, but I can make her change direction if I look down so that I can only see her feet. Then I visualise her feet moving in the opposite direction and I can change it. But I can't change it while looking directly at her. I still can't figure out how the image can look like it's spinning in either direction.

Because you have no spatial reference for forward and back once the other foot's shadow disappears off screen. At that moment her sticking out arm could be pointing towards you or away from you and you can forget momentarily where it was before. or something
Dunno what this has to do with brain hemispheres though. (part two of that comic should be a warning video to brain hemispheres who fool around and show the guy's seizing half getting cut out.)

I found this "test" a few days ago myself. I see it spinning clockwise but I can also reverse it if I focus hard enough.

When you see her going clockwise, it's her right leg coming towards you, in front, and then away (right to left). When she's going counter-clockwise, it's her left leg going away, around behind her, and then back towards you (with the same right to left). The silhouette takes out all the depth information, so it's ambiguous between the two.
For me, it switches pretty easily when I want it to -- helps to cns'ly think "now in front; now in back" or vice versa -- sometimes on its own if I'm not paying attention, sometimes in the same spin (like she starts going right then turns left).
As for what it has to do with right or left hemisphere, I suppose it has to do with which lateral end it privileges as coming towards you ... if you're focusing on the middle, then the right side of the image (hitting left of the fovea) is going to the l.h., and the left side is going to the r.h. So whichever side is dominant is going to privilege attention to that side. Then there's probably cues on both sides that would make the leg look like it's coming forward on that side, so then it's just a matter of which gets priority. Or something like that.

I stared at her body (more like nipples) for a moment she was somehow spinning in the opposite direction and now I can't reverse it!
That's funny... I got the same effect from staring at her crotch.

clockwise cru :cool:

At first I thought this was a gullibility test to see who claimed they could see it go clockwise, as I could only see it go anti clockwise, no matter if I tried hard, or tried to catch it out the corner of my eye. But I looked at it with my head upside down (I've got a cool detachable head BTW), and I could see it go clockwise. But I still can't see it go clockwise with my head the proper way up.

I saw it anti-clockwise at first but if I look at her feet only I can reverse it any which way. I get the impression, thought I may be wrong, that the way you see it going at first depends on the position that you first see her in.
