Then, of course, the mischief takes over and the movement gets very marked. The contorting nose—you’ve also got to love those titles—is funny, but there’s also a second formal question. We know that he’s pressed up against a flat, transparent surface. Still, how is he doing this?
One fun puzzle leads to an answer, which only opens up the next fun puzzle. What a great junior high art teacher he would have been!
