[pygame] scenegraph options

[Doug Holton <d.holton@vanderbilt.edu>]

Hi,
  I saw an earlier note about interest in incorporating a scenegraph
into pygame (see quote below).  A scene graph for games, not for 3D.

Are there any example scene graph libraries out there that are similar 
to what is wanted for pygame?  Something like sForzando or pyOSG or some 
java scene graph?  Or could you share your games that are written with 
scene graphs?

I could use this for a simulation where I need to use a graph 
representation anyway.

sForzando:

pyOSG: (has some errors when I run it)
http://sourceforge.net/projects/pyosg
