Behaviours of Light is a temporary installation that examines light, surface, and spatial experience through the convergence of digital projections and analogue constructs. The design of the piece fulfilled a requirement to transform an entire architectural space. Using a minimal budget, carefully selected materials, and two projection sources, the installation seeks to physically occupy a sliver of air space, while phenomenologically registering on the walls, ceiling, and floor of the designated location. To accomplish this, the work uses a suspended modular surface of translucent and semi-reflective triangles. Each unit acts as a tool to sculpt light, casting temporal geometries and caustics into its surroundings. The environment of Eckhardt Hall at the Winnipeg Art Gallery becomes not only the infrastructure work, but the essential register for these phenomena.
