Unlike with many other icon themes, this one comes with a complete, fully "colorized" usual icons + a full darker version (Monochrome), tool-bar icons, especial icons for mounted devices, etc. Few days ago the developer has updated Faenza to its official 1.0 version!.
This may not bring huge list of new stuff, but to mention few things such as...
*. A lot of icons added for Gnome Shell.
*. Enhanced icon support for the Xfce desktop.
*. Fedora auto-plus and release notes, SEtroubleshoot, etc new application icons.
*. All applications in 16x16.
*. Added a new status icon for: "nm-device-wired-secure" notification... are the "what's new" in this release.
You can easily install Faenza 1.0 icon theme in Ubuntu 11.04 Natty Narwhal, 11.10, 10.10 and even in 10.04 by using the official PPA channel. As usual, open your Terminal window and enter the below commands.
sudo add-apt-repository ppa:tiheum/equinoxThat should do it. OR if you use any other distribution, say Fedora 16 for instance, then you can just download the icon archive from here and then extract the content. Change your directly through command-line to the extracted directory and enter the below command.
sudo apt-get update
sudo apt-get install faenza-icon-theme
./INSTALLThis should open-up a window asking you to choose a distribution using their respective logos. Choose your Distro and the Gnome menu icon and hit enter. Later if you wanted to un-install it, then again come to that extracted folder and issue the below command.
All the proper information can be found in this Gnome Look page, from the developer himself. Good luck.
