Mountain Shell is a new Gnome Shell 3.4 theme that is designed with the aim to bring the beauty and the elegance of the new Mountain Lion OSX to Gnome.
The theme is generally minimalistic, and provides maximum usability for everyday usage. If you were looking for a nice theme to combine the Adwaita Cupertino gtk3 theme that we covered a few days ago, give this one a try. The result will amaze you!
I tested this theme in Gnome Shell 3.5.91 too, but it doesn’t work quite right. DzaDze who is the creator of Mountain Shell also did a modification of the Adwaita Cupertino to be used with this theme that you can find here.
