Marble Light Projecting on Stair Hall Fabric

Vivid ribbons of red, blue, and amber light stretch across a textured beige fabric draped over a concrete step. A clear glass marble sits centered on the cloth, acting as a prism for the cool, flat light entering from a high north-facing window. The monsoon sky outside diffuses the sun, eliminating harsh glare while allowing deep, quiet shadows to pool along the gray tiled walls of the Chicago stairwell. Geometric bands of color pulse rhythmically against the rough weave of the material. The marble itself reflects the muted gray of the surrounding tiles. A sharp edge of crimson light cuts across the fabric fold near the bottom right corner.
