Limelight is an artistic study in the use of complex curved geometry to amplify and direct sound within an open air setting. Sited within Lee Lifeson Art Park, Limelight was conceived as the visual centerpiece and functional focal point for a small performance space which anchors the park’s newly constructed amphitheater seating.
Based on the principle of the parabolic reflector, Limelight was intended to remind viewers of the dynamic geometry of sound and light reflection. The sculpture is a simple and effective way to transform formal and informal performances into memorable and unique experience within the public realm
Limelight is set on a wood deck, which provides the stage for performance. The artwork is anchored to a concealed foundation below the wood deck. It appears to arise from the ground plane, creating a visually powerful and seamless backdrop for sound-based events on stage.
The undulating surface of the artwork is clad in black glass mosaic tile. The tile patterning emphasizes the complex curves and edges of the shell-like form, creating a dramatic and dark figure against the park’s green foliage and lawns. The glass tile is both light-reflective and light absorptive, serving to enhance the acoustic and visual properties of the artwork.
The complex geometry of the shell was evolved using parametric modelling software, under the working title of “Acoustic Shell”. The semi-domical form provides some inherent structural capacity, based on the arched form of shell, in plan and in section.
The curved ridges which create the unique sculptural character the artwork originate at a central focus, and are reflexively articulated on both sides of the shell. The concave/convex form of the shell speaks to paired artistic themes of positive and negatives, inside/outside, light and dark, and shadow and reflection.
While the curves and ridges converge to create a subtle radial pattern, both sunlight and ambient artificial light amplify highlights and shadows that create a visual sense of great depth, due to the glass mosaic finish. The highlights draw the viewer’s eye to the central point, from which sound waves are focused before being reflected back out.
Limelight is a visual and spatial exploration of acoustics and reflection, and anchors a place for creating and experiencing music in Lee Lifeson Art Park.
