Galaxy 3D Space Tour Screensaver

This screensaver lets you get up close and personal with a highly detailed galaxy. Upon launch, you don't actually see the galaxy, but as the camera zooms in, it comes into focus. Once the galaxy is at the forefront of your screen, it spins and moves, giving you a good view of the stars and other matter inside. Galaxy 3D Space Tour Screensaver's graphics look quite realistic, but we must admit we did miss sound effects. Also, the movement of the galaxy was a bit choppy on some older PCs we tested with. If you experience this problem, you might try toying with the slider that slows the animation. Other customization options include the ability to specify the amount of stars in the galaxy and a check box for enabling random camera angles. The trial version does subject you to a nag screen, but it's fairly unobtrusive and moves around a lot, so you still have a decent view of the galaxy. Sci-fi fans and astronomy buffs are this program's target audience, though other users might also find it worth having.
