Creating a Linux-theme reminiscent of art-nouveau and old drawings related to astronomy, science, and mythology.

Genuinely this looks cool as fuck!

I love this

Very stylish, very sober, beautiful. Great work !

The same author has a nice (though unfinished) “retroism” theme, which is a synthesis of w9x and classic mac os aesthetics, at the same time not trying to closely mimic either of them. https://github.com/diinki/linux-retroism

Very professionally designed

Awesome! How long did it take to design all that art, or are you using off the shelf stock graphics or something?
