ASCII FizzBuzz
Part of a programming challenge I was given was to write FizzBuzz ( https://en.wikipedia.org/wiki/Fizz_buzz ) in five different languages. And being a fan of the demo scene, this gave me as good of a reason as any to program up an old school text scroller.
This code requires aalib ( http://aa-project.sourceforge.net/aalib/ ) which is a fairly old ascii art GFX library which handles the hard work of virtualizing a VGA display and representing it in ASCII.
Demo Time
