@hikari I'm curious to see if there will be more attempts to bring textbooks into a new medium to help address this; there have been a few attempts in the maths / graphics worlds (e.g. Interactive Linear Algebra and the Graphics Codex), but authoring seems too difficult as a whole, and it's not clear what form that would take for other fields

@philpax feels like there's a gap here. we actually had these magical tools for creating interactive content: "adobe flash", "adobe director" and so on. but they're all functionally dead if not actually literally so.
