This is AmarokFS theme that was design for my idea of Amarok Screen Saver (http://www.kde-look.org/content/show.php?content=45729) which was implemented (http://www.kde-apps.org/content/show.php?content=52641) by Jan Zarnikov (thanks!).
BC ZenHarmony is as close as is possible to look of my original concept. It doesn't have control buttons, but it's simple and clean. It's perfect for those who use keyboard shortcuts (as I do), remote controllers or wireless mouse, for controlling amarok.
