KSplash/ML is now an integrated part of KDE, and is now maintained by Ravikiran Rajagopal. The official KSplash/ML website is located at:

http://www.eleceng.ohio-state.edu/~ravi/kde/ksplash.html

The following themes have been ported to Ravi's optimized ThemeEngine library. If they had not previously worked with your KDE desktop, they ought to work now.

Contributed ThemeEngines
As I mentioned above, KSplash/ML supports third-party splash screen engines now. This means that your splash screen can literally look however you want it to, with a minimum of effort. I will provide an example for developers to use as a guideline. Remember that these are binary programs. You will need to configure, compile, and install them on your computer in the same manner as any other program, before you will be able to make use of them.

Contributed Themes
You can install Themes into KSplash/ML by using the "Install New Theme..." button in the KSplash/ML Control Center Module. Theme files are simply special tar files, which contain one or more subdirectories holding your theme(s). KSplash/ML uses a few special files to manage the theme, and present it to you in a logical manner. Please see the EXAMPLE theme archives for hints on how to put together a KSplash/ML theme. I will accept new themes at any time, provided that they are archived in an acceptable manner prior to being sent to me.
