I've always been wondering what that flying thing is. A brick?
Its an extremely geeky joke.
It's Schrödingers nyan cat :D
Basically, in quantum theory, one cannot determine a particles properties (with math) without looking at it. Schrödinger examplified this with a cat that was in a lethal deathtrap-box. The cat could be either dead or alive, but you don't know until you open the box. So one could say that the cat is in a state of being half dead/alive, and the act of opening the box either kills it or makes it live.
Thats why the question mark/dead cat/alive cat blink above and under the box.
The thing the box is pooping is Schrödingers equation, the fundamental equation in quantum theory.
