Aurora shows how reflections are created by both the shape of the light and the shape of the reflector. This reflector is a large curved sheet of brushed stainless steel. The ridges in the steel act like tiny mirrors, each reflecting an image. When the images from all the ridges add up, they blend into a single elongated image that looks like a ribbon of light. The many-colored tiles of the exhibit allow visitors to experiment with both the shape and color of the reflections.
