I'm apparently firmly right brained. But, if you read the description, it fits.

RIGHT BRAIN FUNCTIONS
uses feeling
"big picture" oriented
imagination rules
symbols and images
present and future
philosophy & religion
can "get it" (i.e. meaning)
believes
appreciates
spatial perception
knows object function
fantasy based
presents possibilities
impetuous
risk taking

Now it fits.

:D

That's what she does with me too!

It is a cool optical illusion but the right brain/left brain stuff is just BS that has been added on by somebody as it moved through the internets. This is about the third time I've seen that make the rounds but the first two times it was just presented as a cool optical illusion without any mention of brain dominance.

Here's a Yale neurologist talking about it. Neat, though; I go through periods where I can switch her at will (there are tricks to it but I usually forget them between viewings) to being perpetually stuck in one direction no matter how hard I try to switch it.

I just made it switch directions.
If I concentrate on the foot that she has on the ground, I can do it.
:)

I think it's more a bisexualilty test with which way the nude girl spins, than it is a left-brain right-brain thing.

Major mojo to LSPE.
My entire office is huddling around computers trying to figure out how to change the direction of the spinning chick.
:D

Mostly counter-clockwise, although using the looking-only-at-the-legs trick I can make it flip to clockwise. The default, however, is counter-clockwise.

When I started, it was counter-clockwise - then I read for a bit, and she was going the other way. It takes a bit of work, but I can change her direction... does this really mean anything (other than that it's a cool optical illusion)?

It means your mind has the power to control the interwebs.
