Our note
A hand-painted paper style explains in Japanese why the sky is blue by day and red at sunset: a paintbrush draws the sun, splits its light into coloured bands, scatters blue around air particles, then compares short and long paths through the atmosphere with a curved earth diagram. The author says this was a quick trial of an explainer video with Claude Fable 5.2.
Written by The Frontier Brief after watching the video (Nov 10, 2026). It describes what is on screen; we have not run the work ourselves.
