The best teams of the 3D projection scenes were invited to Berlin for the World Championship of Projection Mapping. Theme for their concepts was “Lights of Freedom” in connection with the 30th anniversary of the fall of the Berlin Wall. The artists were faced with the great challenge of presenting their understanding of freedom in connection with the fall of the Berlin Wall and the peaceful revolution 30 years ago and to communicate with the public what consequences the events of that time had on citizens of Berlin and their environment.
