Bliss is the default computer wallpaper of Microsoft's Windows XP operating system. It is a virtually unedited photograph of a green hill and blue sky with clouds in the Los Carneros American Viticultural Area of California's Wine Country. Charles O'Rear took the photo in 1996 and Microsoft bought the rights in 2000. Due to the success of Windows XP, over the next decade it was claimed to be the most viewed photograph in the world during that time. In XP Bliss Slug nature has claimed back the hills and Monitor Slugs have returned to their feeding grounds.
