Haven't seen stitch-maps, that is useful.

I've also been thinking about what constitutes a "good" encoding, and it definitely comes down to individual preferences, even preferences in a given moment. Today you're reading off a sticky-note and want to optimize for size, tomorrow you're laying out 3 notebooks for a huge project and want clarity.

I like the idea of a creator making the base pattern, and then sharing a link that lets the user customize the output encoding.

That customization could be visual (I want a different random seed that is used to parameterize different aspects of this pattern, so it's totally unique to me) or in the notation.

I think it'd be awesome to have a recursive notation editor. So you'd click on a variable and it expands to the verbose representation, which might include other nested variables that you can further expand (or not).

(side note, I hope you don't mind: Game Programming Patterns made a huge difference for me early in my career, thank you for bringing that into the world.)
