this theme fades in another detail of the so called "beth" theme with every starting service (and cites the short poem »von lauten blumen«, too). it relies on the ksplash-moodin-engine to run at all.
it is part of my kde eyecandy collection, so maybe search for the kdm theme and wallpaper as well ;-)
(they're all called "angstalt_beth")
right now a screen resolution of 1280x1024 is needed to get it displayed correctly. if you got the ksplash-moodin-engine running, installation should be as easy as described below ("how to install"). otherwise see the README file for more information.
