“The Rubin Museum of Art opens on Oct. 2 with kite flying on the West Side piers, a Himalayan dog parade and some 100 fluttering prayer flags by contemporary artists. An infusion of $60 million has transformed a decommissioned temple of haute consumerism into an elegant, multihued jewel of a museum, designed by the architect Richard Blinder of Beyer Blinder Belle. Its 70,000 square feet, decked out in bright red, green, gold and blue, comprise America’s largest, boldest and most significant museum devoted entirely to Tibetan and other Himalayan art.” The whole gaudy enterprise is the brianchild of collector Donald Rubin, who bought the building that became the museum on a whim back in 1998.
