The most complex Hello World program

A „Hello World“ program is a program that dipslays the text „Hello World“ on its output (e.g. a screen). Hello World programs are used as examples to show how a program works. The primary idea of a Hello World is to be as short and simple as possible.

For a long time now, I was thinking – just for fun: How could I create the most largest, complicated and complex Hello World ever?

By chance I found a pretty good candidate :-)
