Yes, they do exist - Visionary Clients for New Architecture, the title of a book from Prestel (£14.95). It has contributions from Thomas Krens, Gehry's Guggenheim Bilbao patron, and Rolf Fehlbaum, whose Vitra complex in Weil-am-Rhein includes designs by Tadao Ando, Nick Grimshaw and Zaha Hadid. Decide for yourself, though, whether LA developer Frederick Samitaur Smith, commissioner of buildings by Eric Owen Moss, is the client from heaven or hell. 'Fortunately, the day we met Moss was reading Eliot's Four Quartets, he says. 'I told him I wanted to do a building based on Cervantes' Don Quixote and another on Joyce's Ulysses.' The resulting works were, says the modest Smith, 'revolutionary': 'There is a clock on the wall which does not work and represents the timelessness of Don Quixote.'
