In the pubication 'Prospector. A Casting Eye on Haus-Rucker-Co and Post-Haus-Rucker' Zamp Kelp, one of the founders of the legendary Viennese collective of architects and artists, sets out his intellectual cosmos and examines his performances, objects, and architectural works in terms of their contemporary relevance. Luftschlosser compiles photographs and texts from the Zamp Kelp archive, putting them together with collages, drawings, memories, and essays written specially for the book. Science-fiction stories and biographical notes as well as freshly edited essays - some of them previously unpublished - on architecture, landscape, the city, space, and virtuality contribute to a comprehensive portrait of the visionary architect, Utopian, and professor.
