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.

A website to see a map of the world's tides, and bidirectional predictions for individual stations (edit: worldwide too, forgot I added that). The UI/UX is... archaic, but that's just how I wanted it. It works fully offline. https://solunar.pages.dev

Most fun part was transcribing 70+ year old NOAA tide calculation mathematic/astronomic/hydrologic research papers into modern TypeScript. Approach is semi-documented here: https://github.com/JacksonKearl/solunar

Looks nice, would love something like that for Europe.

Unfortunately while US's NOAA provides all the data needed free of charge (with an API to boot), the UK government's equivalent charges an MSRP of £38.30 and requires finding and contacting an authorized distributor, though the data does seem to be more worldwide. I haven't seen other offerings.
