Cool optical illusion
Steve Higgins of Omni Brain swore his spinning dancer video is ambiguous. Swore it can be seen as spinning both clockwise and counterclockwise. I could only see it spinning clockwise at first. Then, after staring at it really hard, I can to understand why in theory it was ambiguous, but I couldn't see it that way. Now Andrew Sullivan has a still, which allows me to see the ambiguity. I think I caught it spinning counterclockwise once. But now it's spinning clockwise again, and I can't get it to change.

Weird, it was initially clockwise for me, and as soon as I glanced down to the paragraph underneath it started spinning counter-clockwise. Now I can't get it to switch back.
I find that when I can't get it to switch, looking down at the feet and avoiding taking in the whole scene helps.
Focus on the first letter of the first word of the writing below the dancer, and let her fall into your peripheral vision. When I do that, she switches direction.
