I've written a program in C for exactly this kind of simulation. It's capable
of doing eg a 1000 particle-simulation. It outputs a pov-scenefile from time
to time, which can then be rendered and joined to an animation. It also
supports
collision and fusion of two bodies to a bigger one. If someone is intereseted
i
can post the C-program or an animation which i've computed this way. But don't
expect any kind of Userinterface. I've everything hardcoded in the source
because
of lazyness :)
The Program still is very basic, it uses Forward-Euler integration. I plan to
extend it with Runge-Kutta integration for extra speed and precision.

That's it so far.
Tell me if anyone is interested and i'll post it.
