The exhibition „Supervision“ explored the intersections between art and criminology. It took place in Atelierhaus Salzamt in Linz, where usually no museums guards work. Contrary to his routine a security and museum guard was encouraged to stand in front the art works in the show and thereby deny the visitors gaze on them. Every fifteen minutes, another artwork was covered by him, the performance ended when the last visitor left the room on the opening night. This work was created in collaboration with Leonhard Muellner and repeated in another exhibition.
