I love this sort of thing. Yes, as remarked by probably everyone here over the age of 40, we have had loads of terminal shiny stuff for decades. However, here we see the tradition continue at least one or two human generations later and in a modern programming language.

It's funny that despite the fact that GUIs with mice, menus and things have been around for a bloody long time: you can't beat a terminal prompt for many tasks. Mind you my terminals these days looks rather better than the twinax connected beasts of yesteryear that I looked after. I don't remember transparency options on those.

Have a look at https://github.com/nojhan/liquidprompt for more eye-candy for your prompt - it does look rather good and I've been using it on one machine for at least a year with no snags. However that project may be needing an active developer judging by the last commit and Issues.
