Aerial Photos: US Cities Screensaver (36 photos) provides an attractive slide-show presentation of aerial photographs of U.S. cities. Although the images aren't breathtakingly beautiful, they are rather interesting depictions of the mark we've made on the planet. The program is powered by an excellent screen-saver engine, which lets you adjust the time between slide changes, show pictures full-screen or at original Taille, mute the relaxing MIDI-based soundtrack, use up to 23 transition effects, and take advantage of Microsoft Plus! support. Bureau- and tray-based screen-saver Utilitaires -- which work with any Windows screen saver -- are included as a bonus. You may run this nag-free trial version up to one week before purchase is required to continue.
