I'm the creator of Ubuntu SE and I thought I'd share the story with you...
I work in software development and have been using Linux as my main desktop for 20 years. I've tried lots of distros, but on the desktop you can't really beat Ubuntu (as long as you avoid Unity, but that's a different story).
I'd been using Ubuntu for a while when Ubuntu Christian Edition was released. As an atheist I though this was a pretty daft idea - why would anyone need a religious Linux distro? So, in the name of satire I created Ubuntu Satanic Edition, Linux for the Damned. It's hard to believe it was released in December 2006, almost 9 years ago.
I've always been into heavy metal and this influenced the look and feel of the distro, taking the symbolism often used in heavy metal artwork and applying it to the wallpapers and colours of the desktop.
What started off as a couple of wallpapers expanded to screensavers, boot splash screens, icon sets and sounds. I even started making custom ISOs for the distro and running my own website, forum and package repository. I even sold a few t-shirts and mugs.
It was quite an outlet for my artistic side and I created a range of artwork, including original creations done in GIMP and Inkscape, and raytraced images using Povray. I also edited my own and other people's photos. It was great fun. I even got to do some coding as the boot screens and screensavers were written in C.
It caused a bit of a stir when it came out, and seemed to attract all sorts of nutters, included people who thought they were actual Satanists. There are 666 comments on the original "About" post! We also got banned from distrowatch, which was a laugh.
Before long, I found myself running the exact thing I'd set out to satirise; a religious Linux Distro! I guess as long as I was aware of the irony that made it OK, right?
Trying to make the distro something more than just a different look, and wanting to include more of the original influences and my own interests, I started including Creative Commons licensed metal music on the CD. This was a way to spread the word on some decent up and coming bands from around the world and felt good to do so.
Interestingly, the colours used in the standard Ubuntu distro became much darker and it started to look surprisingly similar to SE... whether we were an influence, I have no idea.
After about 5 years I kind of got bored with the whole thing. I had kids and had got heavily back into my guitar again, so my spare time was taken up with other things. Ubuntu SE is still available, but it's based on such an old version of Ubuntu now it's hard to get any updates. I have no plans to continue its development, but the wallpapers are still available if anyone wants to download them.
All in all it was a good way to explore both my inner artist and inner geek, and I learnt a lot. I hope a few other people enjoyed it, too.
