In order to use the word spin you must have an axis.. for me the axis is from the bottom of her foot(the one that is moving LESS) to the top of her head (this is the most reliable axis you can take... by that I mean this is the axis where her spinning is the most concentrated) There is no wrong answer this way.. anyone who said its obvious which way she is spinning is fucking stupid.
It has a lot to do with 'insufficient data' to the brain. See the pics I posted above. You can't see her elbow or whatever and your brain goes "Oh it must be behind" or "Oh it must be in front" and makes everything else match up the same way.
Can I get a response from someone other then charliemurphy (the tl netter not the comedian that guy is fucking hilarious)
I think most people are thinking of viewing from above.
If that were true then everyone would see it as counterclockwise....

maybe my heads playing tricks on my but if i stare at it for like 1 minute its going counter-clockwise, but then if i read some posts down in the topic and look back its switched

you are fucking stupid. Charlie has it. It only works because each frame can be interpreted as her front or her back. Once your brain finds a "solution" to the silhouette, it will cling to it and make everything fit into that scheme.

only if when they said clockwise they were thinking from below. There's obviously some confusion that needs to be cleared up if you were thinking that everyone was viewing from below and I was thinking the opposite. we'd need to come to some agreement about how to view it or state "clockwise from above" or "clockwise from below". seems at the moment, there's a chance people might all be agreeing with each other about the rotation, just not the viewing position.
A parallel light silhouette taken from one side is an exact mirror image of the same type of image taken from the opposite side.
It is a mathematical fact that if you don't know the chirality of the object (i.e. which hand is the left and which the right) independently of the image itself, you can't know which side you're viewing it from or which way it is turning.
However, I believe (without being certain) that this image is not a parallel light silhouette, that it was based on a perspective image, and that it does reveal that the dancer is turning to her right.
Note: I did not read the thread so excuse me if this was already mentioned
first of all, this is really cool
second, i was having a lot of trouble getting it to go back and forth, but i figured out a way to get it to change on my own accord.
If you right click-> view image then there is a picture of the image next to the URL that is much smaller. For some reason i can simply look at that image and decide which way its spinning, then just glancing down at the big picture will change it as well.
yes, "turning to her right" or "turning to her left" is a better way of putting it. Viewed from above, clockwise=="turning to her right". either way, I agree with funchucks in that it is a real 3d image which has been flattened and there is a definite answer. I agree that she's turning to her right.
I think I have been starring at it for 20 minutes trying to figure out what creates the illusion.
My conclusion is that it is like Charlie Chaplin's mask:
Now although my first impulse was to see it ClockWise, I can see it both ways. However, once Im convinced it is rotating in one given direction, its almost impossible to switch to the other without looking away from the picture.
There are two ways I can change rotation: Using the peripheral vision, and tricking my brain into thinking its rotating into a determined direction before I look at the picture in full focus. Or I can just cover the whole picture, except her pivoting foot. Now I try not to make any inferences about her foot (ie: if its a right or left foot), and I imagine its facing away from me, turning clockwise as it goes up, or counterclockwise as it goes down, as it was saying now. From there i can choose an inference and start the rotation on whichever way I want.
Curious thing when she is rotating Clockwise, she is using her left leg for support. When she is rotating Counter Clockwise she is using her right leg to pivot. Very interesting indeed. =)
This is weird, i see both (not simultaneously). One moment I was staring at it and I was like, duh it's counter clockwise, how many way can an animated picture spin? Then I read some of the comments, then looked again and holy shit, I saw it going clock-wise. Weird!
Yeah this is freaky I was trying so hard to look how it could be going counterclockwise, then stared like a meter above my screen and suddenly saw a shift in the movement
Haha that is SO cool :D I saw counterclockwise at first but now I can switch between them. They way I force a switch is to think about whether or not her outstretched arm is in front of her or behind her.
For clockwise: When her arm moves from the right to the left of the image, her arm is in front of her (ie pointing towards you as it rotates across). When her arm moves from the right to left of the image, her arm is behind her.
For counterclockwise: When her arm moves from the right to the left of the image, her arm is behind her (pointing away from you as it does a semi cricle), and vice versa with left to right.
Now pick what you want, and just imagine in your mind her arm being in front or behind her at the right time while staring at her. After a couple of rotations I can usually get it to flip.
