Oomox is a tool that allows creating different color variations of the popular Numix GTK2/GTK3 theme. It features built-in presets, so you can easily generate various themes without much effort, or you can use the tool to change the theme colors individually.

Ozon OS "Hydrogen" alpha is based on Fedora 20 and it uses GNOME Shell and Gnome apps by default, customized with various extensions. The newly released alpha is aimed at developers and ships with only part of the Atom Shell: Atom Dock, Launcher and Panel, so it's not really interesting for regular desktop users. However, the beta (and obviously, the final release) should include a lot more exiting stuff.

Quick update for Numix fans: a new Numix PPA has been created and it hosts daily builds for Numix GTK theme, two Numix icon themes, a Plank theme and even a Numix wallpaper. More Numix related artwork will be added to this PPA in the future.

Furthermore, Numix GTK theme is now compatible with GTK 3.4 and Pantheon (it already supported GTK 3.6 and 3.8), meaning it should work properly in Ubuntu 12.04 and elementary OS 0.2 Luna.

The GTK3 theme many of you have asked about in our previous posts has been released: it's called Numix and it comes a flat, modern look with square corners, a dark panel and dark window theme with dark menus.
