Schauspielhaus Graz

"Wenn ein Haus träumt, dann schläft es nicht" (When a house dreams it doesn't sleep) was an interactive light installation by Muda Mathis for the facade of the Theatre of Graz, Austria. The human activities inside the building were registered and transformed into a RGB light show. The light modules were installed on 21 windows of the theatre and expanded outwards like bellies. Eight sensors were placed at different spots inside the building to register the activities.
