What would be a few ideas/concepts from programming that I can have on paper and hang on a wall as art?

And by that I mean any piece of code, or an idea presented in pseudo code, something which is very important and is almost art now. I intend to put up a few paintings and work on paper around my office which depict engineering, rather celeb开发者_Python百科rate engineering. I want them to be not so ordinary like e=mc2 or anything too common or geeky, like 42. They be special, they be important and have earned the position of being almost sacred owing to their contribution to their field. So I want a representation of computer programing as well. I hope I'm not asking this in the wrong community and apologies already if I am. Thanks for your time.

I'm surprised no-one has mentioned this ASCII fork bomb yet:

:(){ :|:& };:

It was presented as art in 2002 by Jaromil, AKA Denis Roio.

Should fit on a poster:

You can get the infamous DVD DeCSS code on a poster. I'm sure there's more, I just can't think of any at the moment.

SOLID (Single responsibility, Open-closed, Liskov substitution, Interface segregation and Dependency inversion) is a mnemonic acronym introduced by Michael Feathers for the "first five principles" named by Robert C. Martin[1][2] in the early 2000s[3] that stands for five basic principles of object-oriented programming and design.

Lisp in Lisp. Decorate as appropriate. Short, sweet, and revolutionary.
