Diller & Scofidio have got to be the most interesting architects of the day.  They’ve recently created the High Line in New York but I first came across them earlier in this century when I went to the Brasserie in the Seagram Building. I couldn’t have been more enthused by their sense of play.  Other delights have been the vice & virtue glasses (one even with hypodermic), the Blur Building in Switzerland and lately the ‘chandeliers’ with Swarovski crystals.
