Make short motion-design films entirely in code with an AI agent

A developer wrote one prompt per visual style, from cel animation and isometric 2.5D to a cyberpunk HUD, and had Claude produce fifteen 10-second films purely as code. Each film is a web page (SVG, Canvas, WebGL or Three.js) that can render any frame, captured in headless Chrome; a per-film Python script synthesises music and effects from an instrument sample library, and ffmpeg muxes the MP4. After each cut, a second AI scored it against a rubric and the agent revised twice. All films, prompts, source, a renderer and a prompt template are public. Scoring was AI-only, with no time or cost figures shared.
