With a little practice I can make her turn both ways, but I find it's much easier to move her counter->clockwise than the other way around. I saw her counter by default.

#22Can someone explain how this works (I mean how the lady can look like she is rotating in either direction). If I focus really hard on her foot I can make her change direction, but I can't figure out the illusion they are using.
The illusion is created because the figure is rendered side-on with no perspective. Because there's no indication as to which direction is correct, your brain just picks a direction and that's how you perceive her moving. Once your brain becomes fixated on one direction, it's hard to change your interpretation.
(Apparently there's some sort of correlation between hemisphere dominance and the preferred direction, and between the ability to change direction and IQ score. I'm sceptical on both counts.)

#23Putting aside the claims about IQ, did anybody else have the picture start acting really funny as you shifted between viewing it clockwise versus counterclockwise?
I had something that looked like a conflict with the figure trying to go both ways at the same time and jumping between the two.
I found it a fun little exercise.

#24It seems that no one has claimed not to be able to do this so I will. It's driving me mad. I spent at least 5 minutes on it. I cannot see how she could possibly appear to be moving counter-clockwise.

I found that for me I can easily change the direction depending on which foot I focus on in my peripheral vision. I don't know if that'll help. The initial shift from clockwise to counter-clockwise gave me a headache/weird feeling inside my head.

#27I see it both ways after 4 minutes. But I didn't get it initially. Can this be practiced? Just focus anywhere on her body (butt or straight foot), after 10 to 40 seconds, it just automatically switches.

Using your hands to block part of the image -- try the top, bottom, or top and bottom (revealing only the middle) may help.

#30When I read this article, I thought, I bet the comments will have a bunch of people saying, I can see it both ways with the "but I'm way below 160" added for humility.
Almost as if I had peaked ahead of time, that is exactly what I found.
Just a funny observation as I see it all the time. When there's an article about an especially bright young kid, you get a ton of "i was doing calculus at 5 years old" posts.
