star wars theme

I haven't but you can use Eagle Mode to zoom around your system if you're so inclined.

That's a bit like flying around in Star Wars.
Probably easiest just to Google that as a search term together with whatever DE you are using. For example:
"Star Wars theme Gnome"
"Star wars theme KDE"

has anyone seen a star wars theme for linux?
What desktop environment are you using?

Gnome-look and Cinnamon-look have a good selection of themes.
