FS Icons by Frank Souza is a beautiful icon set for Ubuntu that will give your desktop a new fresh look.
The icon set was updated only recently with more application, devices, action icons etc. and If you want a different icon set than Faenza and Awoken, try it out.
To install the icon set, run the following command:
sudo add-apt-repository ppa:kroq-gar78/ppa
sudo apt-get update
sudo apt-get install fs-icons-ubuntu fs-icons-ubuntu-mono-dark fs-icons-ubuntu-mono-light
Now use Gnome Tweak Tool or My Unity to switch icon theme.
