Left Brain or Right Brain?

I thought so at first as well, but remember this is a still a pure 2D image (no depth information whatsoever), anything that seems 3D is your imagination.

 

It means you're going to make a psychiatrist very wealthy... )

 

Funny guy:grrhee:

 

2D will clearly distinguish left from right. Watch her head tilt to her left shoulder with her left leg extended.

It changes direction when the legs and head/shoulder are aligned toward the camera so you can't see the change of direction.

Addendum: My daughter and I watched simultaneously and thought it was spinning in different directions. So much for my theory

 

Alright. Got it figured out now. The optic tract from the retina to the brain is diagrammed as below:



Therefore when the image is in the left field (or to the right of the observer) it goes to the left brain which establishes tracking and translation of the 2D image into a 3D perception in your brain. (And vice versa)

Watch the figure rotate, then read the text to the right while keeping the figure in your peripheral vision, then look back at the figure. If it didn't change-repeat but look at the text to the left.

 

I can make it go either direction on command now by simply reading the column on the left and moving my eyes (not my head) to the figure. That makes it go counter clock-wise. To get it clockwise- I read the column on the right then move my eyes to the figure.

Pretty cool.

 

I saw counterclockwise, then when I started thinking about which way is clockwise, she changed on me. Everytime I thought about something really hard, she'd change directions on me. It was vexing.

 

yeah- my daughter and I saw in opposite directions at the same time which immediately disproved my initial hypothesis.

I believe is has to do more with how your brain extrapolates 2 dimensional information into a 3-dimensional perception. The perceived rotation depends on which particular (left or right) visual fields are stimulated as to track on to the object. The image will be assigned to your the left side or right side of your brain.

 

too easy.
