The last time I was working on one of these, I discovered the phrase http://en.wikipedia.org/wiki/Turing_tarpit

Not that these are all a waste of time or anything, you just need to remember not to take them too far.

A turing tarpit is a whole different beast. Brainfuck and whitespace are examples of a turing tarpit.

This is just codegolfing.
