The code is intentionally somewhat vague. I don't want to spoil the easter eggs to people who read the diff of this pull request :)

Not vague enough :D I don't have a porcupine repo cloned atm, but I already know what it does :)

I don't think I want this to be more vague, because users need to be able to trust Porcupine, after all. If it looks like this hello world program I wrote many years ago, you can't really tell whether it is a cryptominer or a harmless easter egg.

At least you had fun reading the code :)

lol, that's a cryptominer. I don't trust it.

Yeah, it was definitely amusing :)
