Summary:
Program that simulates the movement of stars
Description:
XStar is a Unix program that simulates the movement of stars. It starts by putting a bunch of stars on the screen, and then it lets the inter-body gravitational forces move the stars around. The result is a lot of neat wandering paths, as the stars interact and collide. Along with the program, there is a fairly large document that explains the N-Body problem in a fair amount of detail. It doesn't get into the gory details of the "real" N-body solvers, but it does give you an overview of the techniques they use.
