Holy shit this is beautiful. Does anyone know is this theme is available for linux mint 18.3 or if there is something similar?

That's showcasing a gnome theme so I doubt cinnamon will cut it. If you use gnome just install the theme pack and use tweak tool to set it. I tried it on Manjaro but decided the Manjaro material gnome theme is the best ever.

Tried it yesterday on xfce. And it doesn't look so great for me, returned to default.

Maybe would be best if I made something like this for Cinnamon...I'll give it a shot..now, lets google how to make themes

@duckduckgo also have a look at vimix theme it's very similar
