Geometric light play through cut crystal in arcade

Cool blue twilight falls through a glass roof, striking a cut crystal object that fractures the light into sharp geometric shards. Bright white facets slice through the dimming ambient air, casting prismatic triangles onto a smooth, dark surface below. The crystal's precise cuts catch the fading daylight, creating a mosaic of hard-edged highlights and deep shadows. Soft reflections bloom on the surrounding glass walls, mirroring the fractured beams in muted tones. The cool season air hangs still, allowing the light to settle without distortion. A sharp, diamond-shaped highlight rests against the edge of a wooden beam, anchoring the floating patterns in physical space.
