This application provides a sandbox environment for experimenting with the effects of gravity. It offers the following features:

• Simulation of gravity in three dimensions
• Objects of varying size can be added to the scene with arbitrary initial trajectories
• The predicted path of the object is shown
• Objects merge upon collision
• History trails are drawn for each object
• The simulation speed can be adjusted
• A force grid shows the gravitational potential
• Objects can be made static
• An actor can be added to the scene with a dedicated chase cam
• Targets can be placed in the scene to be collected by the actor
