Clockwise

I’ve seen repeated links to this left versus right brain thing.  I’ve looked at it repeatedly and found nothing changes the fact that she is spinning clockwise.  It doesn’t change with time and staring.  It doesn’t change with peripheral vision.  It doesn’t change by noting that her posture strongly suggests counterclockwise movement that makes the actual clockwise movement look strange.  She’s spinning clockwise, and apparently I am not succeptible to whatever optical illusion is involved.

Update:

Intriguing.  Deb was able to see this going the other way… sometimes.  So I stood there with her and watched it on her computer.  She periodically saw it go the other way.  For me it never changed, apart from it comes to a stop sometimes if there is enough activity from other stuff on the page.  It seemed to be the times it stopped that triggered her seeing it go counter-clockwise.

Since we both watched it at once, it has to be a perceptual thing, not just a trick where, for instance, some people load a different version when they view the page.

Update Later:

I see, it appears to be an optical illusion associated with the shadow of one of the feet, which always appears to go counterclockwise, whichever way the rest seems to go.  I could get it to change by focusing on the foot that’s going the opposite way, basically as suggested in the comments.  Weird.  Usually that sort of illusion is more obvious to me.  Then again, in that craze many years ago of prints you had to look at funny to see the picture in the fuzz, I almost never could distinguish a picture.

Update after Wizlanche:

If you guys like the spinning girl optical illusion, you might also like this ferris wheel, which for me is far more responsive.

1. Try covering up the whole figure except the shadow of the foot--that was how I got it to change, and then I uncovered the head and the foot and from there I could get the whole thing to go the other direction.
