Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

I was studying maths as a hobby and made myself a LaTeX editing environment in Emacs with inline rendering of mathematical content: https://github.com/dandavison/xenops

A handful of other people use it I think but I made it for myself and don't have time to maintain it when I'm not studying maths.
