Laurids Ortner, Günther Zamp Kelp and Klaus Pinter of Haus-Rucker-Co, Oase No. 7 at the Fridericianum, Kassel, Germany, 1972 (via spatialagency)
'Taking their cue from the Situationist's ideas of play as a means of engaging citizens, Haus-Rucker-Co created performances where viewers became participants and could influence their own environments, becoming more than just passive onlookers. These installations were usually made from pneumatic structures such as Oase No. 7 (1972), which was created for Documenta 5 in Kassel, Germany. An inflatable structure emerged from the façade of an existing building creating a space for relaxation and play, of which contemporary echoes can be found in the 'urban reserves' of Santiago Cirugeda. Haus-Rucker-Co's installations served as a critique of the confined spaces of bourgeois life creating temporary, disposable architecture, whilst their prosthetic devices were designed to enhance sensory experience and highlight the taken-for-granted nature of our senses, seen also in the contemporaneous work of the Brazilian artist Lygia Clark. Contemporary versions of such work can be found in the pneumatic structures favoured by Raumlabor and Exyzt.'
