Re: They woke up
Malbolge is over-engineered. Use something elegant, like Unlambda. Only three operators to learn, and their functions are trivial to remember.
While the Turing Tarpit and malevolent languages are fun, the best esoteric languages are the ones that someone intended in all seriousness to be used for real work. Someone_Somewhere mentioned NNAPL; another is the scripting language for the prosody analysis tool Praat. Array indexing by string interpolation is clearly a programming-language innovation whose time has come.
