A basic version is easy, yes.

It makes no attempt to analyze when stable state is reached, has no way 
to add heuristics, has no output or save format, or indeed input format. 
I haven't hacked it into vacuum because I don't have GHC 6.10 installed.

All that being said, it's a quick proof of concept, it comes with some 
fun examples including most of the platonic solids and a couple of 
chemical modules. It may be a starting point for someone wanting to do 
something cleverer.

Compile with -threaded. It bundles my simple Reactive implementation 
which separates the framerate from the simulation speed and lets you 
rotate / zoom in/out.
