Spinning silhouette illusion (Mind Hacks - USA)
She appears to constantly spin in one direction, but if you concentrate hard enough... voila! She spins in the opposite direction!
Brainz are funny things.

I'd seen the spinning silhouette illusion before but never got it to work. I just gave it another try and I succeeded. The trick is to "defocus" to the extent that you see two of the spinning ladies - both spinning the wrong way. Actually, while writing the previous sentence, in a window adjacent to the spinning lady, she was spinning the wrong way as I saw her through the corner of my eye. Interesting...
When I first saw this illusion she was already spinning the "wrong" way (anticlockwise). After concentrating for a little while I can switch her direction at will.
For me, the trick is to concentrate on different parts of her body.
If I focus on her chin or her extended foot, she tends to spin clockwise.
If I focus on her extended hand, she tends to spin anticlockwise.
If I focus on her boobs, she tends to oscillate back and forth such that her back is always facing me.
That's just not fair!
