[Visualpython-users] more physics examples?

Hello.
I recently downloaded and installed the Windows version of VPython.
It looks quite nice.

For my first Python program, I coded something that seemed difficult 
[for me] to do using VRML with EAI/Java scripting.



http://www.physics.syr.edu/~salgado/software/vpython/EFieldBuilder.py

It allows the user to assemble electric charges in space
and see the resulting electric field vectors.  

It's version 0.99 because it seems to crash once in a while.
When I have more time, I'll try to reproduce the problem.

I would appreciate any suggestions for improvement.
Thanks.

P.S.
Where can one find other physics-oriented vpython programs?
