The original Shiftie theme that I made for Shift Linux - http://shiftlinux.net/
I finally decided to upload it here. :p
Metacity theme included.
To use the start-here.png (shift logo) icon you'll need to put it in your current icon theme's 48x48/places folder and backup+remove any icons that are named start-here.svg/png. Your icon theme should be located in /home/username/.icons/.
If you're using an OS default icon theme you may need to open the gconf-editor and select to use a custom application icon in the applications-menu.
