The 8-Bit Cities project, which started with 8-Bit NYC, is an attempt to make the city feel foreign yet familiar, smashing together two culturally common models of space: the lo-fi overhead world maps of 1980s role-playing and adventure games, and the geographically accurate data that drives today’s web maps and GPS navigation.

Remap Berlin, by Marco Cadioli aka Marco Manray, spreads a thin geographical virus in Google Earth and deals with different levels of reality. The project introduces a series of b&w photographs shot in Twinity, a mirror world that reproduces a realistic 3D replica of Berlin. The photos shot in Twinity, are then geo-localized in Google maps, re-mapped from virtual to real and positioned in the exact point where they have been shot in the mirror world. Once uploaded in the photo sharing community Panoramio, the pictures are mixed up with other ones shot in the same geographical point from real life users. Many of these pictures have been selected by Google and can now be found as “Popular photos in Google Earth”: his became a little geographical virus, parts of our memories of the real world. The photographs are cityscapes, shot by Marco Manray roaming around the still empty streets of Berlin in the beta version.
