About me
Now retired, I was teaching computer science in Geneva at the Cycle d'Orientation (12-15 years old children), and working on the use of computer at school.
Now, I'm going on working for the French speaking Squeak community. See the wiki of the french Squeak comunity
I have written a visual scripting system, V-toys using Etoys. A special subset of tiles is intended to very young children (with more visual feed back) that are not able to read. The normal V-toys enabel collaboration and exchange of projects between children speaking different language.
