Variety changes the desktop wallpaper on a regular basis, using user- specified or automatically downloaded images. Variety sits conveniently as an indicator in the panel and can be easily paused and resumed. The mouse wheel can be used to scroll wallpapers back and forth until you find the perfect one for your current mood. Apart from displaying images from local folders, several different online sources can be used to fetch wallpapers according to user-specified criteria - Flickr, Wallbase.cc, Wallpapers.net, NASA Astronomy Picture of the Day, Desktoppr.co. Media RSS feeds from Picasa, deviantART or any other place are also supported.Variety can also automatically apply various fancy filters to the displayed images - heavy blurring, oil painting, charcoal painting, etc. - so that your desktop is always fresh and unique. Heavy blurring for example is a great way to get abstract-looking and unobtrusive, yet colorful wallpapers, similar in spirit to the default one in Ubuntu.
