This public sculpture will be created from cylinders of pure cast glass, made of sand collected from deserts across the earth. Over four-hundred cast glass columns will combine the desert sands into a clear, wave-like form, mimicking a desert dune. Visitors can interact with the artwork, walking alongside and through it, where the glass will subtly melt into the landscape, like a desert mirage. It will have strong material presence, connecting to the elements. Social and connective, Mirage will create an unexpected gathering place for visitors and staff. The glass columns are glimpsed through the trees from the Visitor Center, the highway and beyond, generating a sense of discovery. • The artwork has been created together with Katie Paterson.
