Oh no! That spinning dancer!
This image always renders me somewhat crazed, because I find that, depending on which areas I focus on, she seems to switch between clockwise and counter-clockwise rotation. What's more, upon observing a switch, I find myself fundamentally baffled as to how it looked as though she was rotating the opposite way previously, and it's always extremely difficult to determine where to focus my eyes so that she'll 'switch' again.
At the time of my voting, she appeared to be rotating counter-clockwise. I have an ASD.
