I used the Gear Stone wallpaper by shanesemler, found here:http://www.kde-look.org/content/show.php?content=7600

to make the main orb thingy, and slicker icons for the icons. slicker icons are found here on kde look.
Like all of the recent semi-trans splashes (altho this is fully transparent, more sort of shaped) you need the same kdm wallaper as your dseskto wallpaper if you want it to look right
enjoy!
