Nelson Rockefeller, a great patron of modern art, commissioned this sculpture in 1978 to update and enhance the lobby area of the International Building. Although each element is unique alone, together the ten units are a single work of art, creating a haze of light that lessens the cold steel and stone of the modern lobby and entrance. It involves nearly sixteen hundred rectangular metal leaves with gold patinas individually attached to vertical stainless-steel cables. The sculptures embody the essentials of reflected light and movement, two qualities typical of Ihara’s work.
