Brainfuck

More obfuscated programming

Brainfuck is a minimalistic programming language, described elsewhere. Its beauty lies in its simplicity, and trying to use it is a truly fascinating experience.

Here is a little something from me:

                            Linus Akesson presents:
                   The Game Of Life implemented in Brainfuck

        Type for instance "fg" to toggle the cell at row f and column g
                   Hit enter to calculate the next generation
                                 Type q to quit

Download the program

Here is an example of some typical output generated by this program. The user first enters some data for an eight generation oscillator, and then the program calculates the rest.

New world record in BF Quine size...

The Portable Brainfuck Interpreter (by Urban Mueller, who also created the language) has an undocumented feature: Because the program and its data are kept in the same array, it is possible to write self-modifying Brainfuck code. Regard this simple Quine:
