Heh, for the longest time I could only see her rotating clockwise and had no feel for how one would see her moving counterclockwise. I stared at just her feet, one eye at a time, cross-eyed --no difference. I finally managed to see counterclockwise rotation by focusing on her non-pivot leg. But while I can see that for maybe one or two rotations before switching back, it frequently looks like she's just swinging her leg back and forth now rather than rotating in a complete circle.
Oh well, I don't put too much stock in it--I already knew I was a bit unsettled (read "crazy") in the head having characteristics of both the right-brained and left-brained--who needs a test for that?
