Matthias Wermke is teaching a seminar (Zweckfreie Räume - Intervention und Performance) with four students at ETH Zurich (Department of Architecture and Art, Prof. Karin Sander) on the topic of "appropriation and theft in art". Later, this very technical title is changed to "Absenz – das Abwesendsein von einem Ort" (absence - being absent from a place ).
