A tiny man inside a larger mans head views a theater projection of an egg being cooked.

The Cartesian theater is a little theater room inside the head of a human in which a tinier version of the same human views the life of the big human as a movie and controls the big human. The theory for such a headroom was first posited by René Descartes who claimed that: "I think, therefore a little clone of me inside my head am." Some neurosurgeons have attempted to discover and safely extract the little human for neurosurgical reasons. Right now, the little human is enjoying a movie about an egg.
