  OK, my parent comment is obsolete now. Post title has been revised.

Slightly non technical question about these. After looking at this and BF esolang derivatives, are these esolangs essentially a category of intermediate representations that would be useful for automated software analysis? Given you can encode the language anyway you want (e.g. Ook), and while they aren't efficient for writing and running programs, they are simple, consistent (if large) inputs into an analysis engine. Is this considered a thing?

  You're better off going for lambda calculus. Which, admittedly, looks more like an esolang than anything else

    Unlambda is an esolang based on this concept

Some of the sample programs are kind of amazing: http://www.dangermouse.net/esoteric/piet/samples.html http://www.dangermouse.net/esoteric/piet/samples.html Hilarious idea.

  The Pi calculator text just made me burst out laughing, waking my girlfriend + baby. Still worth it.

I bet the people who write this language has no concept of "time" in the way they perceive the world, therefore able to time travel freely.

There used to be a couple guys that would submit solutions to the qualifying round of the Google Code Jam (the round with the 25-hour time limit) in this language. I think he had to zip a png file containing his program with another file explaining of how to run it in order to submit.

  Looks like it was done twice in 2010 (https://www.go-hero.net/jam/10/languages/Piet https://www.go-hero.net/jam/10/languages/Piet) and once in 2015 (by me!) (https://www.go-hero.net/jam/15/languages/Piet https://www.go-hero.net/jam/15/languages/Piet) I sorta cheated with an assembler (https://github.com/sl236/Piet https://github.com/sl236/Piet) though.

Many more esoteric languages are on the esolang wiki: https://esolangs.org/wiki/Main_Page https://esolangs.org/wiki/Main_Page Enjoy :)

Taking inspiration from this, my friends and I made a programming language where each program is chess games: https://github.com/VitamintK/Passant https://github.com/VitamintK/Passant
