Ubuntu 13.04 Default Wallpapers Released [Download Link Included]

We have a winner or should I say winners? During every release cycle, Canonical conducts a wallpaper contest on Flickr through which they select the final set of default wallpapers for Ubuntu. Ubuntu 13.04 Raring Ringtail was no different and user submissions crossed 300 mark even though there were strict rules such as one wallpaper per person and similar.
