Any libraries to aid weird shaped source code programming

Any libraries to aid writing programs with source code shaped like drawings (such as http://www.ioccc.org/1998/banks.c or http://groups.google.com/group/co开发者_StackOverflow中文版mp.lang.c/msg/e105e5d339edec01). For any language.

Your second link made my day :D And it really works!

If you want to play with source code, perl is your friend! Have a look at http://search.cpan.org/~asavige/Acme-EyeDrops-1.55/lib/Acme/EyeDrops.pm for an example. I know you want a language agnostic tool, but I don't think such a thing exists.
