With an oversized crystal, which he saw more as tool than design object, the British star architect John Pawson inspired a fresh look at things we know all too well and traditionally venerate. Light refractions, kaleidoscopic fragments, undreamed of perspectives – all this was promised by the lens enthroned under the dome in the entrance hall of the Kunsthistorisches Museum in Vienna. And it is a masterwork even apart from this setting: it is the largest item that the crystal manufacturer Swarovski is at present capable of manufacturing. The personal presence of Nadja Swarovski, John Pawson and Deyan Sudjic, director of the London Design Museum, added extra glamour to this already brilliant evening.
