Caustic Light Patterns on Tiled Wall

Wavy lines of golden light ripple across a wall of pale grey tiles, created by sunlight filtering through a glass of water resting on a wooden step. The liquid inside the glass distorts the glow of nearby string lights into shifting, liquid-like shapes that dance across the grout lines. Deep indigo shadows pool in the corners of the stairwell, against the warm, amber reflections on the smooth ceramic surface. A few droplets rest on the glass rim, catching the ambient glow. The pattern shifts subtly as the water settles, turning the rigid architecture into a fluid canvas of light and shadow.
