First draft of a complete running program. I automatically "tangle" the code from the markup to check that I didn't forget to include something. The picture is blurry, but in practice I can zoom in and out using mouse wheel or pinch gesture. The editing experience is terrible. All the lines are absolutely positioned and not integrated with the markup. But code is read more than it's written 😛

Looks promising! I do believe that it is important to start designing for the reader. Otherwise, as a developer, you will inevitable optimize for the developer side. How would you handle bigger code? By growing the canvas, or by introducing pages?

It's hypertext, so I could have links. I'm imagining links closing some outer levels of detail and opening inner ones. All this is influenced by reading Christopher Alexander on "the fundamental unfolding process".

Ohhh, I should read that. Is that in one of his books? Or some article?

It's "The Nature of Order". Volume 2 of 4 😅

Ouch... The Nature of Order is on my reading list for retirement, as I don't expect to find time before. But retirement is still many years in the future!

It's surprising short given the length, because of the number of pictures. But then I spend 6 months thinking about a chapter.

Reminds me of Haystack Editor.
