Ulrike Hemberger and Rainer Hällfritzsch are members of the Berlin media cooperative Werkstatt für interkulturelle Medienarbeit WIM e.V., founded in 1986. WIM focuses on media literacy and empowerment. Recent projects include fostering cooperation between non-seeing and seeing people through media projects and work with refugee children. In their films, Hemberger and Hällfritzsch (a co-founder of Radio 100, a progressive community station in West Berlin) deal with a variety of social topics and already prior to 1989 documented activism in the GDR such as the ecological movement.
