This wallpaper program turns your desktop into a full-on outer-space adventure. The demo for Desktop Dreamscapes lets you access four of ten out-of-this-world scenes packed with colorful planets, asteroids, and spacecraft. We like that the program often switches camera angles, giving the action a big-screen feel. The atmospheric soundtracks are about what you'd expect and lend the appropriate ambience. Right-clicking on your desktop lets you access the customization options. You can adjust the volume of the audio, have scenes switch at a few intervals, and enable the high-quality video mode. Desktop Dreamscapes didn't negatively affect our PC's performance, though it does take up a bit of hard drive space. Sci-fi buffs will find this program a welcome addition.
