The Cologne-based collective, founded in 1985 by Gerd Arens, Wolfgang  Laubersheimer, Reinhard Müller, Ralph Sommer and Meyer Voggenreiter, was one of the protagonists of New German Design. The large installation staged in the central exhibition hall is the first collective work since the project Café Casino and the d8 chair at documenta 8 in 1987. (Foto: DetlefSchumacher.com)
