Install Ambiance DS Blue theme on Ubuntu 12.10 Quantal/Ubuntu 12.04 Precise/Ubuntu 11.10 Oneiric/Linux Mint  13/12 (Dark GTK3 Theme)

This theme is for those who like Dark themes, personally this theme is my favorite theme with Malys-Uniblue icons. Recently this theme is updated to latest version of GTK and NoobsLab made available for 12.10.

1st Install Malys-Uniblue Icons or Check Icons Collection
You can use these Tools to change theme and icons: Gnome Tweak Tool, Ubuntu Tweak

Theme tested on Ubuntu 12.10 Quantal Quetzal.
