Okay, here is the answer. When she spins clockwise, the right leg is extended. When she spins counter-clockwise, the left leg is extended. This is a clever illusion. I believe if you time it (using only left and right leg extensions) by number of spins for a fixed duration over the course of several screen refreshes, you will see that it is pre-programmed. There are several long periods for both clockwise and counter-clockwise, and then there are some short back and forths. Nothing mental about this. Someone just put it together really well.

counter-clockwise

hihi I kept seeing the lady doing the turn left and right, and never turn it backward to make a complete anti- or clockwise turn! What does it make me then? Left or Right?

try it with one eye covered. depending on which eye i cover it turns left or right. close both eyes and only open one, then close both, think about something else for a moment, and open other eye…. anyone else?

I like you was also skeptical about this test when i first saw it so i asked my dad to come over and take a look. I asked him what way the dancer was turning and he said anti clockwise. I said, “No it’s going clockwise.” and he looked at me like I was crazy and walked away. I tried it with my brother and the same thing happened, but my mom agreed that it was spinning clockwise. It’s completely real.

This image is responding somehow to my movement. If I concentrate on the dancer moving the other way and sort of tilt my body to that side, she will suddenly turn and do what my body is leaning towards. Try it. It seems to be responding to the movement of the person in fron of the screen. Don’t know how, but it IS. … If someone tries it, please comment.

First clockwise…then anti-clockwise…then I can half spin her one way then the other at will.

I see both!!! =] I just have skills and can control the way i see it

Initially, I saw her spinning clockwise only. Focusing on the ‘grounded’ foot, I found that the moment the foot was pointing directly away from me, the spinning would reverse and the girl would start going counter-clockwise in full circles. After a while, focusing on the grounded foot caused the spinning to continually reverse, so that the spin would be 180 degrees clockwise then 180 degrees counter-clockwise, always with the girl’s back towards me and never making a full circle. By focusing on the upper body I was eventually able to ‘control’ the spin through a full circle in either direction, but would have to re-focus on the foot in order to reverse direction. I found a plausible explanation for what is really going on here, one that made perfect sense in light of what I had experienced. It has nothing to do with right/left brain, but with the brain’s inclination to convert a 2-dimensional image into a 3-dimensional one. It was written by a clinical neurologist from Yale University Medical School. See what you think: http://www.theness.com/neurologicablog/?p=27

My nephew, niece and I were watching. My niece and I only saw it going clockwise; my nephew saw it changing. Then my niece started seeing her go both ways. They told me to stare between her legs and then I saw her going back and forth between the two ways.

My whole family has taken the test. I only see the woman spinning clockwise. My husband both ways (I still don’t believe him) My father clockwise and my 3 nephews all anti-clockwise again don’t believe them. I can sit and stare at her for 10 minutes no changes……….. Though it did start a fun 30 minute debate in this household lol….

Try Opening the image in a few tabs (you do this by right clicking select open image in new tab) in at least 3 tabs in the middle tab have this page so you can scroll in down a bit. in the other 2 they should be roughly same location. you can tab over and notice it change as your perception does. you brain is forced to reevaluation the information it is given and make a new assumption. This is what this image does is cause you the viewer to attempt to put a 2d image in your 3d world. this is a great example of your brain trying to make since of none since.

If you concentrate enough, you can make her go both ways. Initially, I saw her spinning clockwise, then by staring at her foot she switches and goes the other way.
