What will be of the few programming ideas / concepts that I can have on paper and hang on the wall as art?

Question

And by that, I mean any part of the code or idea presented in the pseudo-code, which is very important almost now. I intend to lay out several paintings and work on paper around my office, which depict engineering, but rather mark engineering. I want them to be not as ordinary as e = mc2, or something too common or provocative, like 42. They are special, they are important and have earned an almost sacred position because of their contribution to their field. Therefore, I also want to introduce a computer program. I hope I do not ask for this in the wrong community and apologize if I am. Thank you for your time.

Must fit on a poster:

Answer 2

You can get the shameful DVD DeCSS code on the poster . I’m sure there is more, I just can’t come up with any at the moment.

Answer 3

I am surprised that no one mentioned this ASCII fork:

:(){ :|:& };:

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

A WARNING. Entered into the terminal, this fragment generates new processes at an exponential rate until your computer stops and the main processes stop executing. You have been warned!

Answer 4

SOLID (Unified Responsibility, Open-closed, Liskov substitution, Interface segregation and dependency inversion) is a mnemonic acronym introduced by Michael Person for the "first five principles", named by Robert C. Martin [1] [2] in the early 2000s [ 3], which means the five basic principles of object-oriented programming and design.

Answer 5

Lisp in Lisp. Decorate if necessary. Short, sweet and revolutionary.
