In the Orangery area of the garden’s Grand Conservatory, Munro’s installation Snowballs comprises six chandeliers—grouped in threes—that hang above the lawns to each side of the main conservatory walkway. Each chandelier measures more than 9 feet in diameter and is composed of 127 individually hand-blown glass spheres.
During the day, the glass reflects and refracts the surrounding natural light. At night, the glass balls, illuminated by fiber-optic strands carefully laced inside, come to life. The chandeliers change color in unison, sweeping through a subtle palette of white, blue, green, magenta, red, orange, and yellow, using six RGB DMX color-changing light sources and a hand-painted color wheel.
For Arrow Spring, located just past the formal flower gardens to the south of the Peirce-du Pont house, Munro has created a 300-foot-long serpentine trail of four different types of sage plants. Designed to recall the form of a flowing river stream by day, at night it transforms into a shimmery thread of greenery. Munro takes advantage of the sage's silvery-blue quality and highlights it using 16 LED flashlights, staked in the ground, along with bare optic fiber that is weaved and hidden among the plants to create the luminescent glow.
Water Towers is located in the area of Longwood known as the Meadow at Hourglass Lake. According to Munro, this piece "marks the transition between Longwood’s formal gardens and its natural landscape." The light installation is composed of 69 structures, each built out of water-filled 1-liter recyclable plastic bottles stacked on plywood boards for intermediary support. Fiber-optic strands are threaded through all 17,388 bottles and connected to an LED projector with a hand-painted color wheel. During the day, the combination of plastic and water has the appearance of glass, and the towers take on different levels of transparency in the natural light. At night, in the darkness of the summer sky, the towers take on a completely different personality and resemble vertical haystacks of colored light. The experience is further enhanced with a sound track of choral music.
Forest of Light is composed of 20,000 illuminated glass spheres and rods that weave themselves through the part of the gardens known as Forest Walk, a forest of tulip trees, white oaks, and sugar maples. The strands of bare optic fiber that illuminate the glass spheres total 86.9 miles in length, and they carpet the forest floor as they run up and over rocks, ground cover, foliage, and other plantings. As with all of the installations that are part of this celebration of light, the piece has one persona during the day and another at night. By day, the light rods read like a plant species all their own, popping up randomly from the forest floor. At night, when illuminated by 80 halogen light sources with hand-painted color wheels, the rods and spheres gently pulsate in a rainbow of colors that makes it feel as if the forest has come alive. The experience pays tribute to the inherent beauty found in nature and the play of light.
