This program for Windows simulates the collision of two galaxies. Each galaxy has its mass, number of stars, and orientation set by the user. The collision is viewed in two windows, an X-Y, and X-Z view. The facility exists to view the collision from any desired view point via a 3D spatial viewer. The initial conditions of the collision can be saved to file for re-running at a later date. A full help file is provided giving instructions and tips.
