Sylvain,
I just noticed you live in Simcity, a fan of the game? If you are, you might like to know that they released it as open source, a friend gave me the link not two days ago (that does not mean it was opened recently) if you are interested I can pass it when Im back home tonight, or maybe you can google SimCity Open Source...
