Navigate by remembered stars

A dark sidereal instrument: white shell points fix the horizon, sand ribs carry swell memory, and every line returns to the imagined canoe.

Ground

Deep ocean-night blue keeps the compass in open water, never on a printed nautical page.

Signal

Near-white markers act as cowrie shells and star positions; accent appears only on key bearings.

Rhythm

Eight-pixel structure, hairline borders, and coconut-rib diagonals hold the poster taut.

Shell points White markers locate sidereal bearings around the dark horizon.

Sightlines Thin radial rules keep the memory system technical and precise.

Sand ribs Warm diagonals echo coconut-rib wave charts without ornament.
