Ubuntu 12.04 LTS Precise Pangolin is scheduled for release 26th of April. I had an entry in the wallpaper submission group on Flicker, but my photos was not selected this time. Here are the two wallpapers I submitted.
When I were in Namibia in 2008 I took this photo of the sunrise while we were waiting for the gates to Sossusvlei to open. The sky was lit as on fire as the sun came up and the gates opened.
