Ubuntu Look on openSUSE 12.1 / GNOME 3.2.1

Reactions: 
 This post is about changing default Adwaita theme in openSUSE 12.1 / GNOME 3.2.1. I grew bored of the default theme installed on openSUSE 12.1 which is adwaita. I started searching the net and found that it does require quite a bit of work . I have been able to install and use Ubuntu like theme.

Changing themes  in GNOME 3 desktop involves:-
==>Changing "window theme"
==>Changing "icon theme"
==>Changing "shell theme"
==>Changing cursor theme (if required)
Prerequisites:-
==>GNOME 3 desktop needs to be installed(quite obvious)
==>OSS , Non - OSS , openSUSE Update , Community repositories are configured on the machine.
==>"gnome-tweak-tool" or "Advanced Settings" needs to be installed.This can be one through YaST tool
==>GNOME shell extension by name "gnome-shell-extension-user-theme" needs to be installed and enabled through Tweak tool .This step is required because only through this extension can we change shell themes.
