Man... this thing is crazy... it took me a time until i can change her direction... its hard... initially i only could see her spinning anti-clockwise... but with some effort i could make her spin clockwise.
An interesting thing i noted is that when she is spinning anti-clockwise, she is resting upon her right foot, and when she is spinning clockwise she is resting upon her left foot. I think its how they relate the direction of her spin with the cerebral usage.
Maybe we decide what is the direction of her spinning by "overlapping" the notion of our body on her image, thus assigning what is right and what is left for her. When we assign this, the spinning direction is also assigned to her.
Ive heard that the brains right lobe controls our left side, and vice-versa. So, maybe they are supposing that if a persons usually rests its body on his left foot is because its brains right lobe is dominant, and vice-versa.
Concluding... or resuming... if a person has, lets say, the right lobe dominant... then this person will prefer to rest its body upon its left foot. So, when the people sees the image, it will "overlap" its own body image to her image, and so will conclude that she also is standing upon her left foot, and thus spinning clockwise.
Does it makes any sense?... for me it does... but im very stoned so my opinion may be a bit biased... :stoned:

EDIT : I must add that the very moment i change her direction is VERY funny... i cant help from laughing... like... in the very moment it changes its direction, i think the mind stops for a fraction of second... there is an interruption of continuity... something like that... which is very funny... like the very moment you understand a joke... or had a sudden insight... or a deep realization... its hard to describe... but very funny
Coelho Reviewed by Coelho on . Incredible illusion Don't know if this has been posted before. The Right Brain vs Left Brain | Frostfirezoo.com Is the dancer going left to right, right to left, or both? I usually see it going clockwise, but sometimes I see it going counter-clockwise. I do not think that it has anything to do with right or left brain usage, but it's interesting since the image is just repeating itself over and over the same way. Rating: 5
