  "brief": "A dark navy night with a small lighthouse silhouetted on a rocky headland at one side of the canvas. From its lamp a pale, warm wedge of light sweeps slowly back and forth across the scene, fading with distance. Layers of soft fog drift across the frame at different speeds, glowing and thickening wherever the beam passes through them and sinking back to a cold blue-grey in shadow. Faint stars flicker above the haze, and a few slow ripples of moonlit water catch the beam near the bottom. The scene moves on its own, calm and hypnotic, with no input needed.",

  "statement": "A lighthouse on a dark headland, its lamp throwing a pale wedge of light back and forth over a night full of slow fog. The beam is a stack of shortening triangles that add up to a soft fade with distance, and three banks of translucent ellipses drift at different speeds; any puff the beam passes through warms from cold blue-grey to candlelight and thickens, then sinks back into shadow. Stars twinkle above, and the water below holds a faint column of moon glitter that flares whenever the beam sweeps across it. It asks nothing of the viewer; it is meant to be watched for a while.",
