Milan's annual design week, Salone Internazionale del Mobile, turns 50 next April. As part of the global run-up to the festivities, New York will host ''I Saloni Milano in New York,'' a six-week program starting Nov. 29 that will bring a taste of the design world's reigning extravaganza to Manhattan. It's a mini-Salone, in which 20 Italian furniture showrooms (including B&B Italia, Flos and Poltrona Frau) will host ''Italian Christmas'' exhibitions; the director Peter Greenaway's Milan-centric video installation, ''Leonardo's Last Supper: A Vision'' (right), which was seen at the Salone in 2008, will take over the Park Avenue Armory; and the theater visionary Robert Wilson will create video portraits of Roberto Bolle, who dances at La Scala, interacting with an assortment of iconic design objects (Nov. 30 through Dec. 18 at Center 548, by invitation only). Design has always been close to Wilson's heart. ''When I was 8 years old,'' he says, ''in the middle of the night I took all the plates and glasses out of the kitchen closet and put them back in the shelves in a designed order.'' Perfetto.
