Package "variety"

automatic wallpaper changer, downloader and manager
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.
