Longwood Gardens, Pennsylvania, is famous for its skillfully cultivated Victoria amazonica lilies. These were the catalyst behind the creation of giant waterlilies made out of CDs in 2012—a material Munro worked with extensively in the CDSea installation. He also gives credit to two other inspirations. First to C. S. Lewis’s book The Voyage of the Dawn Treader, which depicts a sea of white lilies that signifies the border between two worlds, and second to the painting Sky Above Clouds IV by Georgia O’Keeffe, that shows a clear blue sky populated by abstracted clouds that receded from the bottom to the top edge of the canvas. To see the installation of CDSea have a look here.
