Day-to-night time slice: a single fixed view of a Korean riverside skyline of generic high-rise apartment blocks and a long road bridge, an ordinary unnamed Korean city (not any famous real skyline), and the sky above it, composed of twelve vertical strips side by side, each strip taken at a different hour from left to right — bright noon on the far left, golden afternoon, sunset orange in the middle, blue hour, and full night with lit windows and stars on the far right. The skyline and horizon line are perfectly continuous across all strips; only the light changes. Clean straight seams between strips. No text, no letters anywhere.
