Scott's Wallpaper Switcher is a system tray tool designed to allow you to quickly switch between wallpapers on your windows desktop. You can also configure the program to automatically switch wallpapers at predetermined intervals (like every 5 minutes). There is a built in "boss key" feature where clicking the system tray icon will bring up a "safe" wallpaper just in case you are in the habit of running inappropriate wallpapers on your windows desktop. This software is freeware, and is free for noncommercial use.
