An interesting slideshow someone sent me a long time ago.

The one with the woman moving in a circle and being either "right or left brained" is awesome. I've seen that one before.

I guess I'm part of the 15% that can switch her rotation back and forth!

Kind of an optical illusion but this kind of thing always scares me. Have a go at this test

Same here, I managed to turn her both ways. Awesome.

I enjoyed the slide show, (I'm a right brainer only!) and Savage's test is indeed scarily thought provoking.

This one baffles me, I just follow it round and round...

Hey everyone who enjoyed the spinning lady!
Actually this is what I liked as well, and the reason I posted the slideshow! (btw, I can see her spinning in both directions!)

AFTER posting it, I did a little research & I came across a few websites who had some interesting info about this particular illusion.
Apparently, the right/left brain theory is incorrect.
I'll copy/paste some of the info:

1. All silhouettes are ambiguous. Our brain tries to reconstruct the third dimension (space) from the flat image in our eyes, adding information which is usually realistic, but not really there.
And in the case of a silhouette, there are two equally likely interpretations, leading to perceptual rivalry.
Actually, as some of you commented, and I agree: they are not completely identical in likelihood, because on left rotation the 3D arrangement is such that one looks from below – one looks at the sole of the foot.
That may explain the statistical preference for rightward motion.

2. This illusion made the rounds in the Internet late 2007. And two aspects I find very obnoxious:

   * The original authors copyright was removed. Naughty! Here the material is reproduced with permission (granted Oct 2007, thanks again!).
   * Second, it was accompanied with misguided and erroneous comments about the right and left brain hemispheres, insinuating that a given spin direction was associated with dominance of one of the two hemispheres, topping this with totally exaggerated interpretations of hemispheric specialization, which is strongly overstated in populist claims anyway.

3. During a recent presentation, I performed an informal ad-hoc experiment with the audience: I showed the silhouette for a few seconds, and then asked the audience which way they had seen the silhouette spinning.
Of the 61 women, 49 saw it turning clockwise, 12 anti-clockwise.
Of the 60 men, 50 saw it turning clockwise, 10 anti-clockwise.
Thus there was a close 50:50 sex distribution, and 20% of either saw anti-clockwise rotation.
I conclude: there is a strong preference for initial clockwise rotation, without a difference between the sexes.

On a different website I found the following, which can actually help those who see the lady turning in one direction only:

Spinning dancer silhouette is a bistable illusion where you can see the ballerina move both clockwise and counterclockwise.
It is NOT a brain test to determine which part of brain is more used.
Let the rotating lady on the right and left guide you (by Nobuyuki Kayahara).
