Glow Tide

Waves breaking electric blue on a moonless beach, bioluminescent surf

A night photograph of a beach where the surf is full of glowing plankton: every wave rolls in dark, then flashes electric blue along its curl as it breaks, peeling along the bay, and the whitewater carries the light up the sand, leaving a bright fading edge and sparks in the wet beach, which mirrors it all. Above, the Milky Way and a field of stars; a dark headland closes the bay. Move the mouse through the water or across the wet sand and the plankton light up behind it, the way they do around a hand or a footstep; with music on the surf glows brighter with the bass and the sparks in the sand flash on the beat.
