Install Mountain Lion Theme (GTK 3.6) and Icons from PPA in Ubuntu 12.10 (Quantal Quetzal)

If you prefer to make Ubuntu 12.10 (Quantal Quetzal) look like OS X Mountain Lion, I suggest that you try the Mountain-Lion GTK 3.6 theme, Mac OS X icons are also provided. The theme is compatible with Unity and Gnome Shell and can be easily installed in Ubuntu via our PPA. Here are two screenshots of Mountain-Lion theme under Unity:

Under Ubuntu 12.10, open the terminal and enter these commands:
