As my first Easter Egg post, I advertised the most important French hebdomaire, weekly newspaper, Le Canard enchainé (lit. the Chained Duck), something you can't find in the virtual world. This year it is something more peculiar, literally a virtual (version of our) world. Well, worlds, the bygone ones.
