Ubuntu (oo-BOON-too) is the worlds most user friendy Linus Distrobution and in July a Christian Edition became avalible. Well Satan didn't like that so he set his minions to work and they have created Ubuntu Satanic Edition whitch is just a theme at the moment, but as more people use it and the distrabution's dark powers grow should be getting some more features soon.
A Visual Walkthrough is available so you can see what it is like before you turn to the darkside. Not that there should be any doubt for anybody with a cold heart or one who wants a cool looking theme.
P.S Using the Satanic Edition might be evil, but is still not as evil as using Windows XP.
