Esoteric languages are good fun, to be sure, but it's possible to take the concept a little far.

Brainfuck, for example, is a great example of a minimalist Turing-complete language, expressed as an esoteric. Befunge and Piet are other good examples of languages that approach programming from a different angle. Malbolge, though, is just malevolent and evil for its own sake.

I guess that's the point.
