I'll finish the article when I have a little more time, but I wanted to note that, when I read the intro part on the new feed, she was spinning on her right foot/going counter clockwise, up until I read that she could spin both ways. Then my mind flipped her to the left foot/going clockwise and I can't flip it back. I'll see what happens when I return again and read the full article tonight or tomorrow night.

Update: My brain seems to set to whatever direction I was perceiving last, and I can switch it once by looking at only the shadows, but never back to what I originally saw [not without leaving for a while and doing the shadow trick again]. Trying the shadow trick two times in a row oddly doesn't work.

Update 2: My mind still switches at will every now and again, but looking at only the shadows for a while works too, and now works a few times.
