brainfuck (sort of, its symbol based i.e. '>' means ++pointer, the while loop is [ ... ], etc). I like the Perl latin module, http://www.csse.monash.edu.au/~damian/papers/HTML/Perligata...., I'm pretty sure there's not a practical non-english lang though...
I saw that listed on the wikipedia page. It looked hilarious. But none of the languages listed looked 'practical' other than simply ports/translations of existing languages. I was really curious to see if there were popular and different languages being used in other countries. To me that would be fascinating.
