Comet

The depths of space offer not only wonderful planets like Mars to explore. There are also stars and comets to discover. This screen saver lets you adorn your desktop with your own comet. You can even change its size and the length of its tail. Be careful, though.... if the tail gets too long, it may just burn itself right into your screen. (Of course, no permanent damages!)
