"Befunge is a two-dimensional fungeoidal (in fact, the original fungeoid) esoteric programming language invented in 1993 by Chris Pressey with the goal of being as difficult to compile as possible." - Esolangs
This code is a Ruby implementation of Befunge's interpreter. It means that you can run befunge code inside your ruby application and get it's output during runtime.
require 'BefungeInterpreter' befungeCode = "64+\"!dlroW ,olleH\">:\#,_@" interpreter = BefungeInterpreter.new(befungeCode) interpreter.execute interpreter.output #=> "Hello, World!\n"
