One less useful thing for you:
https://onli.github.io/izulu/. It is a bash script that changes the background of your desktop according to the weather at your locations, and can show the temperature and forecast.
Doesn't have much functional value, but it was easy to write (though over the years it needed some care, mostly thanks to closing weather APIs) and it is a small simple thing I use almost every day, as it is in my autostart.
