A simple Plank theme I made to look like Ubuntu's panels. Includes a hover theme that matches Ubuntu's tooltips.
To install: - Extract the files and place them into ~/.config/plank/ replacing the existing files (this will overwrite the default theme, so back it up if you care to). - Plank should immediately reflect the changes. If not, it will after restarting.
Recommended icon size: 48px.
Updated Tue Dec 11, 2012: Fixed rendering (removed "Renderer" from the section titles).
