30-Second Riemann Hypothesis Explainer Animation

A roughly 30-second Riemann hypothesis explainer animation (about 44 seconds in the final cut), drawn in JavaScript in a portrait 1320×1644 frame. The prompt is a single Japanese sentence that stresses there must be no mathematical errors. The author later passed the silent version to GPT-6 Astra for a calm female voiceover and a soft chime at scene changes. Suited to short math-education videos and classroom demos.
