Changewallpaper is a project mainly written in Python, based on the GPL-3.0 license.
changewallpaper changes the background of GNU/Linux desktops from a folder or art.gnome.org
This software changes the background of your Gnome desktop.
The application has two scripts, one for changing the background from a set of wallpapers, and the other one from wallpapers downloaded from art.gnome.org, so you do not have to provide backgrounds.
Please, read the INSTALL file for installation and set up instructions.
