Here is my master thesis, Reality's Mirror. It deals with intervention art seeking to produce a consequence in society / the viewer. It analyses works by artists such as Jakob Boeskov (DK), Tue Biering (DK), Santiago Sierra (E), Cristoph Schlingensief, (D), Übermorgen (A), 0100101110101101.org (?) and The Yes Men (US). Reality's Mirror explores the grey areas between art and communication, market, politics and ethics.
Unfortunately it is still only in Danish but there is a short summary in English on the last page. Please ask away if you have any questions.
