Fantastic Worlds Free Screensaver 

Space has always aroused people's imagination. In modern times, space photographs have revealed many of the secrets of the Universe. Nevertheless, some images can be seen only through the eye of an artist. This screensaver features many artistic renderings of space places an phenomena. Thus, we can see exotic planets, asteroids, satellites, galaxies and other celestial bodies in different situations. For example, one of the renderings shows an enormous asteroid falling onto a planet. In another, a planet with several moons appears. A third one shows a close view of Saturn's rings, and so on.

The screensaver has a control panel which allows users to customize many of its settings. For example, you can set the video mode, the duration of the images and transitions, and the screen brightness. Also, you can show or hide the frames-per-second counter and the digital clock, which is activated by default. If you decide to show the clock, you can choose between a 24- and a 12-hour format. A great advantage of this product over other supposedly free screensavers is that it does not require that you install anything else, like toolbars and such.
