Gravitator is an interactive realtime gravity simulator designed to simulate large quantities of objects. It allows you to simulate galaxies, asteroid rings etc. This is possible by having 2 kinds of objects, light and heavy. Light objects don't attract any other object, while the heavy objects attract other objects. Gravitator comes with an interactive editor of the world. It can calculate stable orbit for given objects and generate complex objects such as spiral galaxies.

You can also download gravitator_daemon, a non-interactive program used to simulate gravity and store the results in a file. This file can be later replayed with gravitator.
