As I recall, Nicaraguan Sign Language (ISN) developed
very rapidly from a signed pidgin (LSN). Thus, it isn't an
invented language in the sense that Esperanto and Klingon
are invented languages: it grew by natural processes. It's
the only instance of natural-language genesis that has
actually been observed in progress.
