Here’s a Gnome Shell theme inspired by the Android 4.0 Ice Cream Sandwich mobile operating system. It’s designed by tmari0 deviantart user. Ice Cream Gnome shell theme is compatible with Gnome 3.2.1.
You can install the theme by using user-theme-extension in “gnome tweak tool” or you can extract the package and paste the content of the folder to this path.
First make sure you backed up the current theme, in case you need it later
Deviantart link includes the Ice Cream Sandwich wallpaper and font.
