Looking for feedback on a simulation I created to show how using a displacement field can be used for simulating gravity on a large and small scale. http://www.kademco.com/psim/psim.html [Broken] Click multiple times to create points of mass. Each point you add "pinches" the field. There are no point-point relationships here. The points are influenced by the field using a pressure vector derived from the field. Click and drag to create points with initial velocity. Try leaving the settings as is for a bit. Some interesting formations appear. Let me know what you think.
