It's been a while since I've created any artwork (wallpapers from 2008!!), but this week I've actually been very productive. Besides creating countdown banners and a shiny new LDM login screen for Jaunty (more about this later), I've been creating a desktop wallpaper.
As you can see there's a light and a dark version. Available in 1920x1200 (16:9) and 1280x1024 (4:3). Licensed under CC BY AS
