Laurids Ortner, Günther Zamp Kelp and Klaus Pinter of Haus-Rucker-Co, Fly Heads, Vienna, Austria, c. 1969 (via spatialagency)

‘Haus-Rucker-Co were a Viennese group founded in 1967 by Laurids Ortner, Günther Zamp Kelp and Klaus Pinter, later joined by Manfred Ortner. Their work explored the performative potential of architecture through installations and happenings using pneumatic structures or prosthetic devices that altered perceptions of space. Such concerns fit with the utopian architectural experiments of the 1960s by groups such as Superstudio, Archizoom, Ant Farm and Coop Himmelblau. Alongside these groups, Haus-Rucker-Co were exploring on the one hand, the potential of architecture as a form of critique, and on the other the possibility of creating designs for technically mediated experimental environments and utopian cities. The different versions of the Mind Expander series (1967-69), consisted of various helmets that could alter the perceptions of those wearing them, for example the ‘Fly Head’ disoriented the sight and hearing of the wearer to create an entirely new apprehension of reality; it also produced one of their most memorable images.’
