Show HN: Realtime calendar generation with LaTeX

This is a little project I originally made for NaNoWriMo 2021. I was experimenting to challenge one of my most absurd limiting beliefs: "Nobody pays for software on the internet."

This is using LaTeX in a docker container on Heroku.

The PDF files have clickable checkboxes with custom icons, which was surprisingly hard to do in a PDF...so it's a hack.

Revenue has been modest, I didn't really market it much. But, there has been revenue, which was unexpected.

I was too lazy to make a database so purchases and other events are tracked by submitting a Google form in the backend.
