I got the first question right, but not the second.
You don't have to be smart to notice what's going on with that image, just observant. How closely do you look at the details? The way the mask is shaped gives the impression that the back is the inside of the front, but they kind of cheated when they made the back and just used the same image as the front. It's the little details that give it away, like how the bottom of the nose moves across the upper lip. It got me, I didn't see it until it was pointed out. When it comes to whether it's spinning, the top of the mask shows that it is.
I got both questions right.....and still feel the same.
