Idle Background is a new software program that will change your desktop background to specific images listed on the main window.  The images are picked out of the list every minute (or whatever time your specify) and are changed and set to either Tile, Centre or Stretch.  The program will keep looping through the list until you stop the program.  Previews of the wallpapers you wish to use are available and extra tools to ensure that everything runs smoothly.

Idle background will sit in the system tray while its running, ensuring that it does not clutter your desktop.  You can save your images used as lists, which means that you can have several lists of wallpapers to use, allowing you to switch whenever you get bored of your current wallpapers.
