Just a quick recommendation today for my favorite new dark theme for Gnome, GTK, Cinnamon and Xfce. I’m using it right now on the computer that runs Mint 13 with Cinnamon DE and the main computer (shown) with Xubuntu and Faenza-darkest icon theme. This theme looks and works beautifully with all these different desktops. Check it out HERE. There’s also a PPA to add to your software sources for future updates.
