Sunset Caustics on Pool Wall Above Seagrass

Golden hour light wraps the horizon, casting shimmering web-like caustic patterns across a smooth, submerged concrete wall. The water glows with warm amber and soft teal hues, filtering through a faint haze of suspended plankton that softens the distant background. Below the wall, a dense meadow of long, swaying seagrass blades stretches across the sandy bottom, their green fronds catching the dappled light. The scene sits in midsummer clarity, where the surface ripples above create a rhythmic dance of bright lines and dark shadows on the vertical surface. One ray of light strikes a cluster of small, translucent algae clinging to the corner.
