The spinning girl- I've seen that one before and it "worked", but this time it didn't. I can't remember what was different, though. I feel like it has something to do w/ the shadow.
My favorites are #10, where the halves of people move around; and #11, where the black and white picture turns to color.
The spinning lady did eventually change directions for me - I really don't get why that happened (unless she actually DOES change directions and they're just messing with us!).
