I've come across this before, but now I am more interested: https://jdan.github.io/98.css/ 98 #css is a #windows 98 #theme for your #website. It would be really cool to use this to get a #theme for a real #linux #window . I had a quick look and there doesn't appear to be any #linux #libraries ... It would really be a lot of #effort to pull this off, but also very cool.
