I authored and developed an interactive children's book about entrepreneurship and money management. The journey started with Twinery, the open-source tool for making interactive fiction, discovered right here on HN. The tool kindled memories of reading CYOA style books when I was a kid, and I thought the format would be awesome for writing a story my kids could follow along, incorporating play money to learn about transactions as they occurred in the story.
Twinery is a fantastic tool, and I used it to layout the story map. I really wanted to write the content of the story in Emacs and Org Mode however. Thankfully, Twinery provided the ability to write custom Story Formats that defined how a story was exported. I wrote a Story Format called Twiorg that would export the Twinery file to an Org file and then a Org export backend (ox-twee) to do the reverse. With these tools, I could go back and forth between Emacs and Twinery for authoring the story.
The project snowballed and I ended up with the book in digital and physical book formats. The Web Book is created using another Org export backend.

I developed another nifty feature that lets readers of the physical book access an online dashboard of achievements anonymously using secret "magic words" in lieu of requiring personal information. I couldn't muster the effort to write a special org export backend for the physical books unfortunately and used a commercial editor to format these.
