off: ODE Architect



Dear All,

my boss used to use ODE Architect for ODE visualizations. But he would 
like to change and I'm curious if there is a good (and free) alternative 
of ODE Architect. His main wish is to have a big amount of examples 
(indluding visualizations) built in the program.

Thank you in advance (and sorry for the off topic mail but I have no clue 
where to find information about this) for your kind help!

Regards, Zoltan
