counter clockwise

and now clockwise
let me try again for counter clockwise

counter clockwise

Wow! Ok, now I can get her to go whatever way I choose... just takes a rotation or 2. Would love a link to the science behind it...

Ok, Ive got the sister doing figure 8's... next...

Ok, crossed over to the control freak side.... this can't be good!

I can get her to switch now but she won't do a full counter clockwise turn
My daughter doesnt believe its real

what trick are you using to do it?

Muse2NoPharaoh said:

Aside from coffee, how are you doing that?

Imago said:

to be honest it's the first time that i can change the direction (i did this test before long time ago and would never change)

i just look at half of the image and concentrate in the inner of her thigh and it start to go slow down... ..it change that's all

that was fun but cant remember which side of the brain and direction goes along

does someone knows

Pole said:

oups! i wanted to say it started to slow down
i think it's time for me to

Both.

And thanks for the headache

Ah it seems this may not be a timer trick - tip: focus on the shadow of the feet only and you can quickly alternate how you view it.

First I saw her spinning counter-clockwise then I blinked and she was going the other way.

Creepy....

Psychology of visual perception
The illusion has been incorrectly[3] identified as a scientific personality test that supposedly reveals which hemisphere of the brain is dominant in the observer. Under this unproven interpretation, it has been popularly called the Right Brain–Left Brain test,[4] and was widely circulated on the Internet during late 2007 to early 2008.


Bistable perception
Depending on the perception of the observer, the apparent direction of spin may change any number of times, although some observers may have difficulty perceiving a change in motion at all. One way of changing the direction perceived is to use averted vision and mentally look for an arm going behind instead of in front, then carefully move the eyes back. Some may perceive a change in direction more easily by narrowing visual focus to a specific region of the image, such as the spinning foot or the shadow below the dancer and gradually looking upwards. One can also try to tilt one's head to perceive a change in direction. Alternate versions of the image exist in which an additional visual cue facilitates the perception of counterclockwise spin and clockwise spin.

Thank you for the link

So my first impression (though I can see both directions) each time I see her is that I see her right foot is raised.

I assume that means I am a genius, right?

Is there a pole involved??

great fun!

counter-clockwise
