📚 What cool Linux beginner-intermediate project could I do to escape boredom as a retired person?

I'm looking for some projects I could do using either Bash, Python, Javascript, to escape my boredom. I already made a terminal media player, an automatic music tagger, multiple little script, a startup Dashboard Homer style. I'm not looking for professional stuff. It's more just to have fun, learn a bit and keep my brain active. So if you have some good ideas for little project, please I would be grateful 🙂.
