Windows only: If you like mixing up your desktop wallpaper, but not enough to keep a dedicated application running and chewing up system resources, 100dof Wallpaper Rotator will shuffle your wallpaper at boot time. You pick the directory of images to shuffle through and tweak the settings. You decide whether or not the image should be stretched and otherwise maniuplated, and every time you boot into Windows, 100dof Wallpaper Rotator will load a new image from that directory as your new desktop background. After it performs this function, it shuts itself down—much like previously reviewed Fleace, which grabs images from Flickr. You can use BMP, ICO,.JPG, or PNG files as your source images. 100dof Wallpaper Rotator is freeware, Windows only.
