There were many more excellent images than could fit in one screen saver so this is a second volume of pictures from the desert west of Phoenix and at the Boyce Thompson Arboretum east of Phoenix near Superior, Arizona. This screen saver will work with displays set at 256 colors but 16 or 24 bit color is strongly recommend. The link below is for a version optimized for 640x480 displays. Versions for 800x600 and 1024x768 desktops are available for downloading at SouthwestScreenSavers.com. Users may control several options including timing, captioning, and transitions. MSPlus! users have additional controls available.
