From the desk of: Robert

This chick is totally spun out, yo.

The direction that this woman is spinning is different in people.  2/3 of respondents reported that she was clearly spinning clockwise, and 1/3 saw the opposite.  Of the total responses, the same percentage of people (but not the same groups of people) were able to retrain their eyes to perceive the image spinning in the opposite direction.

Me?  Clockwise and damn puzzled that anyone could reverse that.
