Much more practical—although less technically interesting—is 中蟒 (pinyin zhōngmǎng) or Chinese Python, which is a translation of a programming language I could actually see people using. It's not as impressive as encoding data types in grammatical gender, though; it consists primarily of translating keywords, method names, &c into Chinese, and Chinese is close enough to English grammatically that none of it seems all that awkward. You can find it at http://www.chinesepython.org/cgi_bin/cgb.cgi/english/english...
Incidentally, Perl also has Lingua::tlhInganHol::yIghun by the same author; it's the same sort of modification, except with Klingon instead of Latin. That is here: http://search.cpan.org/perldoc?Lingua::tlhInganHol::yIghun
