The flank of an impossibly large ship, filled by a wall of hull panels whose extrusion depths are hashed per cell — a coarse grid overlaid with a hash-gated finer one, so the greebling looks recursively subdivided. A camera skims the surface at a shallow, grazing angle while a scan light sweeps along the hull; as it crosses each bank of panels the little window lights set into their faces flare up, and now and then an entire section goes dark. The near-parallel key light rakes across the relief, dropping every crevice into shadow. Hover to steer the slide, scroll to run the length of the hull, and press to drive the scan and windows to full brightness.
