zzMetaball Screensaver fills your screen with colored spheres that progress in and out of shadow like moon phases.

zzMetaball Screensaver comes in a zip file containing a .scr, which is typical for this type of application. All you need to do is right-click on zzMetaball.scr after extracting from the zip file and select "Install" or "Test" if you prefer a quick peek before adding it. There are no configuration settings available with this screensaver.
