Munro originally conceived the idea for Field of Light in 1992 during a trip through the red desert of central Australia, when he sketched a landscape of illuminated stems that would wait like dormant seeds in a dry desert, to bloom at night. The idea remained in his sketchbook until 2004, when he finally had space and resources to execute it. It has since been specifically re-imagined for sites across the globe. The Discovery Green Field of Light comprises 4,500 radiant, frosted glass spheres atop slender stems connected by illuminated fiber optic. The spheres and stems wait quietly until dusk and then bloom with gentle rhythms of colored light as darkness falls over the park.
