BrainFreeze
Jump to navigation

BrainFreeze is a two-dimensional esoteric programming language derived from Brainfuck. A BrainFreeze program is a connected path of instruction characters drawn across a grid; there is no instruction pointer in the usual sense and no jump table. Instead, the program counter always advances to whichever neighbouring cell contains a character, and the shape of the path; where it bends, forks, and dead-ends; is what determines control flow. BrainFreeze has no input instruction, so programs are purely generative.
