"Blinkenlights, a large-scale installation created by the German hacker organisation Chaos Computer Club, first appeared on the Haus des Lehrers (House of Teachers) building at a public square in Berlin. It transformed that building into a giant computer screen, using the lights in 144 rooms (controlled via a switchboard) as ‘pixels’ to create simple animations and play ‘movies’. Participants and passers-by could then submit their own animations via their mobile phone which were displayed on the ‘screen’. Later, on the installation located at the Bibliotheque Nationale de France in Paris, participants could use their mobile phones to play arcade games on the building’s facade."
