This nicely done 'saver fills your monitor with dancing bursts of colored plasma rendered against a black background. Its animated patterns seemingly explode out of nowhere, entertain for a moment or two, then dissipate into nothingness. Almost each pattern you'll arrange will look (at least) nice and interesting. Often your animations will have some psychedelic effect - you will like just to watch them. Very good in the DARK, 3 meters from monitor.
