"If you watch the dancer's bouncing foot you'll see (I think) that the image slowly changes and then reverses direction."
But I watched and...no change. Then I looked away and back: she's dancing the other way!
Then, if I looked at the text on the left and not the picture I could catch the shifts--and then I pondered how it worked, watched the text and kept the image on the periphery of my vision--the image seemed to be skating along, wobbling the way those speed skaters do.
And then, I could even get the image--for a moment or two--to turn one way and then the other. Very clever! Don't fight forces, use them R. Buckminster Fuller.
Which led me to believe that it's a trick -- maybe the image changes? It doesn't make sense otherwise.
I looked at it for while longer, looked away a few times, watched her switch directions a few more times, and this time paid attention to whether she was standing on her left leg or her right. And that changes too, so I still thought the image itself must change.
But now I've stared at it a good long time, and I've been able to actually focus enough to see her switch directions a lot more often, almost but not entirely whenever I want to.
I am still not convinced that the image doesn't change at some point, though, because I can't see both images at the same time, and usually with these perception-switching tricks I can.
I also tried it on an assortment of willing victims, who all saw something different. At the same time.
Clockwise for me, by default, but I can make her switch by looking at her lower foot.
Trying to make her switch by looking at her arms made me feel ill.
(Although for sitemeter purposes, some possibly might wish that they were....)
I think the count is one anti-clockwise and everyone else clockwise, so far.
(I just checked: she was going counter clockwise in your honour.) Don't fight forces, use them R. Buckminster Fuller.

So...
Er...
