Looking for small, impressive 3D-related Python script

[Kenneth McDonald]

I'm not trying to persuade my company to offer Python as a scripting  
language for their product, but I am trying to give them examples of  
things that Python can do easily that cannot be done easily with  
their current proprietary scripting language. After that it would be  
their decision. As the product is a 3D package, I'm looking for  
something in this field.

This does _not_ have to use PyOpenGL, or for that matter, any Python  
3D package. In fact, my ideal would be a Python script that simply  
uses L-Systems (Lindenmayer systems) as in "The Algorithmic Beauty of  
Plants", to generate plantlike OBJ files that can then be displayed  
in our program. In general, something that generates an OBJ file  
would probably be preferable to something that actually uses  
PyOpenGL, Blender, etc, as then I can just display the OBJ file in  
our program to say, "This is the sort of thing that can be easily  
done by Python without recourse to any other programs".

So please, any suggestions are welcome.

As always, many thanks to this group,
Ken
