With his demands for people to "prove they exist" in an age of total TV coverage and "act, act, act" in the sense of becoming active not 'actors', his work could be considered a direct legacy of Bertolt Brecht, as it demands involvement as opposed to passivity and merely looking on as is the case in traditional text-based theatre. In an age of extreme media fatigue, his was a fresh voice albeit and undisputedly containing echoes of the past, often humorous and subversive yet never cynical. His influences included Joseph Beuys and his idea of social sculpture, and artists Allan Kaprow and Dieter Roth. At the time of his death, he was involved in productions for the Ruhrtriennale and for the Berlin Staatsoper's "Metanoia".
