Gelatin is an Austrian based art collective consisting of artists Wolfgang Gantner, Ali Janka, Florian Reither and Tobias Urban. Gelatin’s work is often raw, brutal and absurd, and often intentionally, but playfully, repellent. The artists have made a “human birthday cake” in which they arranged themselves naked in a circle, with lit candles coming out of their anuses. In 2000, they illegally broke into the World Trade Center and installed a small balcony on the 91st floor (a stunt that lasted a mere 19 minutes or so). In 2005, their projects included a sculpture made from frozen urine and a 180-foot pink toy bunny, which they left to decompose on the side of a mountain in the Italian Alps. Their form of performance-based, interactive art has roots in the 1960s Situationist and Fluxus movements.
