Placement is a programming language designed to be unusable to people who aren't at one of Earth's poles. The interpreter is connected to a GPS and accepts only three commands: !, ?, and :. : clears the program stored in memory, ? runs the program stored in memory, and ! appends a Brainfuck character to the program depending on the interpreter's longitude.
