Activists in Berlin have created a game called Camover where they move through public spaces in disguise, smashing CCTV cameras, recording the act and uploading it to YouTube for points.
The rules of Camover are simple: mobilise a crew and think of a name that starts with "command", "brigade" or "cell", followed by the moniker of a historical figure (Van der Lubbe, a Dutch bricklayer convicted of setting fire to the Reichstag in 1933, is one name being used). Then destroy as many CCTV cameras as you can. Concealing your identity, while not essential, is recommended. Finally, video your trail of destruction and post it on the game's website – although even keeping track of the homepage can be a challenge in itself, as it is continually being shut down.
East Germany withered under the punishing, spying gaze of the Stasi, whose surveillance was always couched in the language of "public protection" and "crime solving." Today, the CCTVs used by commercial firms are an extension of government surveillance, because their footage can be seized, often in secret, in the name of "fighting terror" and similar rubrics.
