to get this go to software center and install cairo-dock core.
(if you dont want the dock in your current desktop just add cairo-dock-core,dont activate,just log out and it should be on the desktop selections.)
now log out and click the icon from where it lets you choose your desktop(cog wheel) and you should see an option for cairo-dock(gnome+effects) log into it.
