Sometimes I find "geeky", cryptic coding funny and even interesting. Today I stumbled upon a "Turing-complete programming language" called Brainfuck (see also the corresponding Wikipedia page).
Of course code (or a language) like that is merely entertaining. I would never like to see anything like that in a production code I might have to maintain. (And, pointing to my previous post, I would never advise a novice programmer to see anything like that for learning purposes.)
Still, the language definition put a smile on my face.
