Instantly saw that it was spinning right, and I can't see how something can spin more than one way, at the same time - mindf**k! - but then, I guess it's an optical illusion?

Cool thread.

EDIT:

OMG! Something just clicked, and I could easily see her spinning left, and then right, and so on! That's so mental, but I love it. Does that mean I has a good, healthy brain? xD
