GoPass
GoPass uses moves in a game of go to generate a password.
...The method is simple: the Custom Seed at the bottom is used to seed a random number generator (RNG). The RNG assigns a value to every intersection on the board. After moves are played, and Make Password pressed, the values of the intersections generate a password based on the game. All of this is done locally. No information is sent outside of the program.
Because go players can remember game moves so well (the information is meaningful), it allows them to use unique passwords for different websites without having to memorize strange strings of symbols (which are meaningless).
