A five-minute thinking game. Begin with one gentle question. End up holding infinity.
the first of three little games: The Circle Game, then Black Holes, then NOW

You just did real mathematics. One thing tending towards another is called a limit, and it is the doorway to calculus, to black holes, and to a very strange thing called now.
