Mostly-configurable Mac-like (see screenshots) drop-in replacement for KSplash. Notice that this is a seperate software package which physically replaces your ksplash binary. Not for the weak-of-heart. This _should_ work with KDE 2.1 and greater, but who knows for sure. Includes a KCM module to help you configure it (each user can set it up differently).
(This is REALLY early stuff. My apologies for it being so crude... I'll be sure to post updates as I make it work better.)
Simple to configure and install. Very configurable (though more improvement is needed).
