Recursive Islands and Lakes (en.wikipedia.org)

As a budding functional programmer, I agree with the spirit of this article wholeheartedly. Recursion, as with nature can blow you mind.

This is probably a bit pedantic but the etymology of the word 'recursion' suggests that the inner islands and lakes would have to form as part of a unified formative process (current), such that the inner islands and lakes were "caused" by the same process operating at a smaller scale. Without such a process, I'm tempted to call this article "Nested Islands and Lakes."
