Every wave below is hand-plotted SVG — no canvas, no video. Drag the moon, raise the wind, and watch high water climb the pier posts in real time.
Three layered wave paths recomputed each frame from sine sums. Crisp at any zoom, weightless on mobile GPUs.
Each harbor has its own bathymetry. Reef Gate doubles the chop; the Cove halves the range but quickens the cycle.
The amber bar tracks the 12-hour cycle. Slack water freezes the computation so you can inspect a single wave stack.
Three wave paths, one phase clock. What the dials actually move.
High minus low equals range. Dragging the moon rewrites both ends at once.
Reef Gate multiplies chop by 1.6. The Cove halves it. Same slider, new harbor.
Freezing the clock freezes the sum of sines. Inspect one stack, then resume.
Keyboard: press 1–3 for harbors, space to pause.
Double-click to open. All waves are path elements recomputed in place.
Crisp at harbor-poster zoom and cheap on mobile GPUs. Dashed currents come free.
