I recently stumbled upon Sleep Sort[1, 2], which is the most creative algorithmic idea I think I have ever seen in code.
I'd love to read about more creative algorithms and code snippets like this, what else is out there? And I don't mean obfuscated code (although they often do include very creative ideas too).
