Rumor has it there might be a new Star Trek movie out. If you haven’t gotten enough of your Starfleet fix, you might want to take a look at this article I wrote for Wired on artificial languages, from Esperanto to Klingon and beyond (fans of Interlingua, Lojban, and Lincos, please raise your hands).
My article was written back in 1993; the world of artificial languages has not changed hugely since then, but I can nevertheless offer a few other links that might interest you. In 1996, I filed a short follow-up article on the efforts of Klingon linguist d’Armond Speers to teach the language to his toddler. Slate recently ran a good piece on Klingon, and you can find a mind-boggling number of artificial languages catalogued here.
