Reading source code

Ted Leung laments he cannot think of any source code good enough to read like literature. Well, I wouldn't claim I grok them but I certainly have enjoyed reading them:

• vsta
• rc scripts
• cii - only so called 'Literate Program' I could bear to read.
• calc (from emacs) - a CAS sadly few appreciate.
• two papers in gopher (hugs?) by Jeroen Fokker.
• programs in Icon and Smalltalk tend to be neat and tidy.

Of course, the above list is not complete.  I'll add a few later if I remember.  Funny I cannot think of any Java source I like reading.
