Circular Restricted 3 Body Problem: A classic. The tool public_cr3bp.zip contains (a) the physics engine to compute the effective potential, the Lagrange points, and the orbits of third bodies, and (b) the mongo subroutine graphics calls to make the plot and movie below. Elliptical Restricted 3 Body Problem: Not so classic, but extra fun as the distance between the binary changes. See the universal solution for the two body problem.
