A weed-based color laboratory, costumes made of bones, guerilla billposting, or subversive alternative street-markings for parking areas: Käthe Wenzel works on the periphery of daily urban life, in urban wastelands and in city systems; she uses weeds, roadkill, and conversation. She explores urban landscapes and "Queer Ecologies" as a transdisciplinary border-crosser with a finely tuned sensory perception for new materials and technologies. She focuses on the adaptability of urban coexistence. "Urban Organisms" encompasses three groups of works-the "Urban Ink Lab", works from Signs and Bones, and Sci-Fi Prototypes. In them, Wenzel hijacks urban spaces: she breaks down wasteland areas in Berlin into micro-localized color worlds; endangered species live on in constructions made of linen and bones; and chopped-up visual vocabularies of the city are opened up for collective reuse.
