Our friends at Carticulate always share cool stuff like this project (they found through The Atlantic Cities, and what I in my turn am happy to share with you guys). In Berlin the 775th birthday of the city is celebrated with a huge map (2.500 meter, scale 1:775). The birthday present is created by eight artists and opens for the public on August 25th. Here is more information on the programme 775 years of Berlin (and where you can find this map on the map).
