Wallpapers for your desktop!
I just recently created two new wallpapers designed for the Linux desktop, but they can be displayed anywhere!
They are both based on a modern concentric circle design. One works with the standard Numix color scheme while the other works with an Arc color scheme.
These themes are so popular, there are now versions to work with GTK and QT desktops. But hey, you could use these on your desktop however you want!
