Hi,
I would like to announce that the strasheela composition system has a new fomus backend (in svn).
You'll find further informations on its home page http:// strasheela.sourceforge.net/.
Particularly interesting might by: http://strasheela.sourceforge.net/strasheela/doc/StrasheelaExamples.html
There is already one more example in svn that deals with a combination of l-systems and constraints.
Cheers,
Kilian
