I use linux quite a bit too tho I like dark themes myself. But I think it would be a cool idea to have a guild theme if you can be bothered to make it up.
So why did you settle on OpenSUSE ? Lots of people went for Ubuntu until they hit that Unity thing and people have been abandoning it like rats of a sinking ship. Lots going over to linux Mint instead which still runs on Gnome desktop. Tho I haven't tried Mint it looks good since both it and Ubuntu were forked from Debian which I am more comfortable with. We used to use SUSE in the Enterprise thing at a place I worked since lots of mainframes/clusters run it.
