Katie Paterson and Zeller & Moye have been commissioned by Apple to create a public permanent artwork at the Apple Campus in Cupertino, USA. This public sculpture for the olive grove adjacent to the Visitor Center at Apple Park, has been created from cylinders of pure cast glass, made of sand collected from deserts across the Earth. Sand from subtropical deserts, coastal, rain-shadow, interior, mountainous, volcanic and fossilized deserts were melted into glass. Over four-hundred cast glass columns combine every desert on Earth into a wave-like form, mimicking a desert dune. Visitors can interact with the artwork, walking alongside and through it, where the glass subtly melts into the landscape, like a desert mirage. The artwork is open to the public.
