This slide-show-style screen saver rotates 36 amazing photos of U.S. Air Force aircrafts . You'll see A-10 Thunderbolt IIs, B-52s, F-15 and more. The package is powered by an excellent screen-saver engine with lots of options: Select the time between pictures, show the photos full-screen or at original size, choose special transition effects, and optionally display the images in black and white for an artistic effect. Plus, each of the photos can be displayed as your desktop wallpaper, and you can choose how often to cycle the wallpaper (in hours, days or weeks, or never).
