I did something like this once using Quickbasic :) It was *very* difficult to
find values to make a stable system.  Either the particles just end up following
their own path, or they collide all, but they never orbit very long.

BTW: a few thousand particles is a *lot* for a system like this.  You need to
check every particle against every other particle!
