Numen/For Use, set designers. This is an international collective active in scenography, industrial and spatial design and conceptual arts. They were inaugurated in 1998 by Sven Jonke, Christoph Katzler and Nikola Radeljkovic. They have worked with opera companies and theatres in Berlin, Karlsruhe, Oslo and Stockholm. In the last decade their focus is towards configurating objects and concepts without a predefined function, an activity resulting in the more hybrid and experimental works which are featured in public spaces and art galleries all over the world.
