Abound Screensaver

This screensaver possesses an extremely simple concept, but its lack of adware and pleasing amount of customization options help keep it in the running. Abound Screensver places any number of variously sized, 3D, multicolor balls on your screen. Some balls stay still, some move around, and some get sucked into black holes. Since this program is so basic, the graphics aren't mind-blowing, but it's clear the developer put some work into them. Still, sound effects would be a nice addition. On the plus side, the program gives you an extensive amount of control over the screensaver's appearance and behavior. For instance, you can specify the number of total, stationary, and moving balls; set the bounciness; and configure the number and strength of black holes. Although some users might find this screensaver unexciting, those seeking a simple, adware-free screensaver might take this app for a joyride.
