Congratulations on the day of the programmer. We decided to make several cards for you and approached this according to the specifics of the date.
Under the cat five scientists and programmers, the code on whitespace, the interpreter and as a result - portraits in the style of ASCII art.

How it all works

Below is a link to hista. The code is written in whitespace, a programming language in which only nonprinting characters are used for control structures: spaces, tabs, line breaks.
You can run the program using the whitespace interpreter. Here is one of the working options .
Run like this:

$ ruby whitespacers/ruby/whitespace.rb hedy.ws
