Have you ever tried to learn a new programming language? I've tried it a couple of times.
The first thing they always teach you is how to get the computer to spit out, which is computer talk for display, "Hello World!"
The second thing they always teach you is...well, I don't know what the second thing is because I'm always so proud of myself for learning how to make the computer spit out "Hello World!" that I quit and go onto the next thing. (Did someone say OCD? Did someone say umlaut? Maybe I should learn German. German chocolate cake would be good for supper. Where's my grocery list? Wait, why am I standing in front of the pantry? I'll just go fold a book until I remember.)
Anyway, the equivalent of Hello World in the book folding universe is to fold the word "Read." One of the first people I saw do it was Isaac Salazar and Heather has a series of articles on RhymesWithMagic with her version. Now I see examples of it all over the Internet.
I'm a little late coming to the party, but here's my version.
By the way, it's not just art, it's good advice.
