This is a modified version of this wallpaper http://www.kde-look.org/content/show.php?content=18356

I give all the credits to the original artist! That's the best wallpapers i've had since a long time, think I will keep it for some time to come!

Tips: it's a transparent wallpaper, so in KDE, try the different gradient fill and blending mode, you can have 1000's different version with the same wallpaper!
