Blue Hour Light Through Glass Sphere on Sand

Cool blue twilight fills the glass-roofed arcade near San Antonio during monsoon season. A clear glass sphere rests on fine beige sand, catching the ambient window light. Refracted beams of soft azure and violet spread across the granular surface, creating sharp geometric patterns. The light bends around the sphere's curvature, casting delicate shadows that stretch across the floor. The minimalist composition emphasizes the contrast between the smooth glass and the rough texture of the sand. No other objects distract from the mix of light and material. A thin, bright highlight traces the upper rim of the sphere where the cool sky meets the glass.
