Spin

[orbsycli]

This was brought up in another forum:

Right Brain v Left Brain | Herald Sun

The guy who brought it up said to look at it, determine if its spinning clock wise or counter clock wise
then close your eyes and create a spin in your mind that spins in the other direction (like visually imagine a whirlpool going clockwise, or counter clockwise. feel it)
then open your eyes and if you did it right the spinner will be spinning in the opposite direction.
I just did made it flip back and forth a couple times by doing this.

A lot of people have been trying to figure out how this works.
Someone even videotaped it with a camera to see if it flips on its own and apparently it doesn't.

can anyone else make it flip,
or can anyone figure out how this psychology works?

it doesn't always work that's why it's boggling.

If you stare at the image long enough to disable your three-dimensional illusion perception, you will see that parts of the black image, like the "leg" at an angle, are swinging back and forth like a pendulum, while other parts are swelling and shrinking amorphously (changing shape).

I don't see it that way. do you?

Cool thingy. I see it rotating clockwise, but can force myself to see it anticlockwise.

[orbsycli]

how?

[Tormod]

I just decide that I want it to spin the other way. It's easy to see how it's just a sequence of stills.

Looking at the feet gives it away completely for me.

The figure changes direction all on it's own. It literally stops then starts the other way after some programmed amount of time has elapsed. The only thing psychological about it is that the figure looks really hot.

[orbsycli]

are you sure?
I havn't seen it do that, yet.

Yes. The figure is really hot and reflects an evolved ideal.

I find no issue with it at all. What I don't get is how they attribute a perception of counterclockwise rotation to the left side, . The more one applies logic, fact and examines detail, the more obvious the interpretation of clockwise rotation.

Now, it's true that it's strictly a 2D figure and so there's no rotation either way, but it's clearly the projection of a 3D figure which is asymmetrical and very familiar. Now it's easy to see from the head and shoulders that the more extended arm is her right one, that when it's going rightward it is to the far side, so a perception of rotation in the other way is incompatible with the highly familiar figure that the shape represents.
