Which programing language to learn, hmmm?

Whitespace "Its name is a reference to so-called whitespace character codes in text files. When a text file is printed, whitespace codes move the cursor ahead without making any mark on the page thus leaving a white space.Unlike most programming languages, which ignore or assign little meaning to most whitespace characters, the Whitespace interpreter ignores any non-whitespace characters. Only spaces, tabs and linefeeds have meaning."
That sounds pretty good or maybe
Piet "Piet is an esoteric programming language whose programs are bitmaps that look like abstract art." Just look at these example programs.
they both seem like very practical choices...

Yup, that was just an excuse to put that picture here.
