Re: Has anyone build a set of gears in Etoys or any other freely available program?

Look there, http://swiki.ofset.org:8000/seaside/SBSuperSwiki and search
with the French keyword 'Engrenage' (gear).
There are four examples.
I am not sure it still load in recent Etoys, you have to try.

Sorry I don't have direct url to give
