This Splash is based on the Glassified Splash and the EOS wallpapers.
Glassified Splash: http://www.kde-look.org/content/show.php/Glassified+Splash?content=84124
EOS Wallpapers: http://websvn.kde.org/trunk/KDE/kdebase/workspace/wallpapers/EOS/contents/images/
The EOS wallpapers are JPG images but KSplashX needs PNG so I had to convert them. This means this Splash is about 8 MB in size instead of about 1 MB but only looks as good as lossy JPG images. If someone knows PNG/other lossless renderings or the SVG source of the EOS wallpapers (or of any/all KDE 4 wallpapers) please tell me.
Btw. this is meant to be used in combination with this login theme: http://www.kde-look.org/content/show.php/EOS+Mania?content=101594
