A deterministic WebGL film of God's Eye View coming online: a seed on Null Island grows into a culture that draws the planet, indexes the surface tile by tile, ingests the live feeds and outgrows its dish, ending on the logo. Renders 16:9 and 9:16 frame by frame in headless Chromium; the procedural score is locked to the same clock. Data and imagery are fetched by the scripts in tools/ and are not committed.
