The physics department I did my undergrad at had a rule -- you could do your computing practicals in whatever language you liked, but they only officially "supported" a few (C, fortran, etc) -- if you wanted help in others, tough. Naturally, this led to some people writing answers in less common languages, like, say, 4-bit assembly for a custom CPU, metafont, and a particularly memorable Ising model in postscript (just print it, and the number of pages is the number of iterations!). It wasn't soon after the last one that a nice little laminated notice appeared saying "please do not send fractals to this printer".
