images of space shuttles at launch, in flight, and landing. 58 images
are in the registered version (12 in the trial version).
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).
