시간경과 등대 건설 - 불모의 섬에서

Timelapse video from a fixed camera on a rocky barren empty island, waves striking black basalt below. Foundations pin into the ridge; a circular footing forms as cranes swing in pre-curved segments. The lighthouse shaft climbs, ring by ring, a spiral stair threading upward through the hollow core. Fresnel housing assembles beneath a faceted lanternyet catwalk rails bolt into the crown. The keeper's cottage frames out beside it, shingles stepping on in tight rowsyet stone paths and windbreak walls appear. Solar arrays tilt toward the sunyet foghorns and weather instruments perch along the parapet. At nightfall, the beam ignites and sweeps the water, a bright pulse lacing the horizon.
