Abound will mesmerize you for hours on end with its colorful balls flying around the screen, bouncing off one another, swirling around and into black holes, in infinitely unique patterns. The elegant beauty of physics in action will soothe and relax you. You can configure the options to create endlessly different configurations, from Jupiter gravity to Moon gravity, super bounciness to steel ball bounciness. Add up to 100 moving balls at one time for truly chaotic action.
