Here's my first attempt at simulating galaxy collision. No collision is handled (no SPH, only pure gravity). No initial velocity for each blackhole, that's why the system oscillate along a straight line. Each black hole represents 90% of the total mass of the galaxy it belongs to. Each star has a velocity set so that it's in a circular orbit around the black hole. Motion blur is activated for sexy looking. Color represents acceleration, that's to say gravity potential.
