GravitySimulator is a real time screensaver simulation of a gravitational star system. Supporting multiple display adapters and multiple CPU/cores. The screensaver will optimise itself to your system i.e. the more processing power you have then the more objects will be displayed.

Insists on re-installing DirectX, even though I had the latest version. Requires a reboot. Tried to preview, but all I got was a dark screen for 5 minutes. Must be heavy on resources, because it took another full minute to get my screen back.
