zufall is a simple program to change the
background periodically. It takes one or more
directories with images as a parameter (no GUI)
and sets a randomly chosen image as background. If
there is a border remaining, its color is the
average color of two corners of the image. This
mostly fits the image very well. It doesn't work
if the root window is hidden by another program,
like in Gnome or KDE. However, it is possible to
execute a configurable command to effect the
change whenever the image is supposed to change. A script to do this in Gnome is included.
