Judy and Josh Weston Pavilion armillary. This armillary sculpture was designed for the American Museum of Natural History Columbus St. entrance and fabricated by ART. Traditional armillaries were used to demonstrate the motion of celestial bodies as viewed from Earth and as an educational tool for navigation. A culture that aspires to interstellar travel would require a new coordinate system so this aluminum and stainless steel sculpture was designed with the Milky Way galaxy at its center and positioned to demonstrate New York City's galactic address-its precise location-on January 1, 2000.
