Add a little variety to your desktop(s).

AutoWallpaper Mac Edition allows you to create different categories for your desktop pictures. AutoWallpaper can automatically resize your images, add borders, filter the image with 14 different effects, and create subtle gradients behind the image that match the colours in the picture. You can even apply effects to an area of the wallpaper to attractively seperate your desktop icons.

Automatically cycle your wallpapers on startup, on program exit, every few minutes (up to 4 hours).
