I love what the Ubuntu guys have done with their distro, and I really commend the awesome Human colour scheme used for their Gnome desktop. Ever since I've been searching for a similar colour scheme for my lovely Suse KDE desktop, and finding nothing I liked for a long time - I took 10 minutes and made my own; Creamy-Human.
Remember, after all - Linux is for human people. :)
Have a great week all, and kudos!
