Mirjam Struppek has an investigation into the variety of screens available in her Urbans Screens project:
URBAN SCREENS is a concept developed by Mirjam Struppek. It investigates how the currently commercial use of outdoor screens can be broadened with cultural content. We address cultural fields as digital media culture, urbanism, architecture and art. We want to network and sensitise all engaged parties for the possibilities of using the digital infrastructure for contributing to a lively urban society, binding the screens more to the communal context of the space and therefore creating local identity and engagement. The integration of the current information technologies support the development of a new integrated digital layer of the city in a complex merge of material and immaterial space that redefine the function of this growing infrastructure.
