Whether computer-animated light installations, light projections or mechanical media surfaces, it is impossible to imagine contemporary architecture without media facaes. This volume "Urban Media Cultures" discusses the potentials of the development of mediated urban spaces in a spatial and social context. International experts from the fields of marketing, technology and culture, e.g. Kerstine Budde from "A wall is a screen", Christian Rhein from the company "ag4", Marc Tamschick, Hank Hausler and many others share with us their experiences with urban media and take a look at what the future holds.
