You won't believe it.. but it is true :)

Funny, first look do gives me clock wise rotation, but just a brief concentration to the image turns rotation to counter clock wise and the if I turn my concentration to the text the animation starts running with clock wise rotation again. This is a keeper, thanks.

What lady? I only see a Rorschach-butterfly
Really like this one and the same for me, the direction of spinning changes when I am looking at the lady or when I am reading the text below her.

Hi Tomasz,
Really cool post very interesting and addictive.
At first i saw it anti clockwise, i looked away then all i see is her going clockwise and its been like that since arghhhhh
-
I can see it either way if I want to. I even tried to see if I could get it to do half turns and reverse, So it looks like it's facing away, then does a half turn and faces you, then another half turn the other direction, and faces you again, as if it had never changed. and it worked. Creepy...

This demonstrates our utter failure to see it as a 2D shape. I got this illusion even in the real world when I sat waiting for a plane. On the opposite side of the runway a radar antenna was spinning, silhouetted against the sky. It was quite easy to make it "shift direction".

This is wild. I can actually take note of the second she changes direction. There is hiccup. A suspended moment when she seems to pause and then she changes direction.
When I first looked at her, she was consistently going counter clockwise. After a while she suddenly changed direction and I couldn't force the counter clockwise again. Until I started reading the text and then she reversed. It seems that when I first looked at her, I was 'analyzing' the situation. Then when I understood the situation, I automatically switched to right brain mode. Once I read, I was back into left brain. If I looked up at her again, she would switch and go clockwise. Wow. -
It's not a default of the "Windows viewer" or a default of the "Navigator viewer"?
-
her posture is for a clockwise direction. Is that part of the visual cues your left brain is using? Dancers commonly lead with their head and outstretched hand.
So far I can see the other direction with it upside down but it goes back to clockwise when I turn it at all back towards right side up.
EDIT: I had it all wrong. When you see her go either way it looks like the same posture. Once I saw her going counterclockwise, I couldn't go back it seems.
-
She is not rotating at all. Just wobling from one side to other. It's hard to see but so it is.

Another method
Blink your eyes and turn your head in the wishing turn wanted -
I just caught a glimpse, just before she was sliding down the pole.
(I gotta get that checked out soon!) -
okay, I checked this out and it is totally debunked here: http://scienceline.org/2007/10/29/ask-hsu-spinning-girl-right-left-brain-hemispheres/
It really has nothing at all to do with left brain/right brain perceptions at all.
Anssi was completely right. It is about forcing a 3D understanding onto something that is 2D.

They are writing that associating left or right hemisphere of a brain with a certain activities is just a theory, which is not really true, but the fact that some people cannot see it spinning clockwise proves that it has to do something with imagination... just see the image I have prepared for you:
I think that image can help those with 'one direction only' find a way to switch. Why? Take a closer look at each individual frame. I can easily see all those intermediate frames between those when the position of the lady IS certain, as a lady facing me or showing her back!Our imagination decides if we see the front or the back because the silhouette doesn't define it exactly.

so maybe you intended to mirror one of the pictures? They appear the same to me.

me?
they're fully different .. i edited that post to put a big space in between the two gifs so you can look at them one at a time -

i think these modifications can really help those seeing only one direction (via the site susan linked to)
counter clockwise
clockwise

Works for me now, though the first one is apt to change direction for a moment.
I was looking to see the differences in the direction of the rings in the background and or the darkness. I honestly cannot see the difference. What am I missing?
PS> "me?" ????

the rings in the background are only so you can see the rim lights that the guy added.. he highlighted areas which force you to see one leg on top of the other for instance.. here's the actual link to where the gifs came from..

i caught the first girl spinning clockwise for several times
-
wow, I totally missed those "rim" lights as I was looking for reasons for the differences. Obviously they were being perceived subconsioulsy nontheless. Now that I know what I am lookin for I see it completely.
Thanks for that!
