A lighthouse that sings ships home. Drag the beam — each heading sings a chord. Ships caught in the light are guided; fog answers in low voices. All sound is synthesized live with WebAudio. No files, no servers.
Beam heading → chord. Eight headings around the rock, one chord each. Hold the beam on a ship to charge its homecoming.
Thicken the fog and the low voices wake — detuned oscillators drifting under the choir. Thin fog = clear bright beam.
Every guided ship is entered. Kept in localStorage — survives reload.
