In 2006 we were invited to create a media installation for the exhibition "Spots" on a temporary media facade at Potsdamer Platz Berlin, in cooperation with "realities united", Berlin. The media facade was covered with a light matrix of 1800 lamps, that could be controlled by a computer, to recreat luminous moving images on the surface of the building. We showed our works "Berlin Sunrise", and "Tokyo Star", to interact with the urban environment.
