Up is down, left is right, clockwise isn't.....

OK, this illusion is freaking me out. Apparently, the spinning silhouette seems to change direction all by itself. This is the kind of trick my brain wants to play on me that's just not nice. If I can't trust my brain to tell me what direction the silhouette is really spinning, what can I trust it to tell me? Huh? What I ask you?

Maybe there's really 2 Häagen-Dazs ice cream bars in the freezer, but my brain only wants me to see one......... yeah!
