Claude Opus 5.5 autonomously wrote all the Python needed to produce a 66-second animated short called Fable — 1920×804 at 24fps, packaged as a single HTML file. Every frame is procedurally rendered: a fox, paper birds, drifting clouds, hand-lettered titles, a full musical score, and sound effects. No image generators, no stock assets, no font files. The model worked for ~2h40m unattended, self-directing the entire pipeline from scene composition to audio synthesis. The moonlit tower-above-clouds frame alone looks like a Studio Ghibli background.

Every pixel and every sound byte was generated by Python the model wrote itself — no external assets of any kind
~2h40m of fully autonomous work produced a complete narrative short with score, SFX, and hand-lettered titles
Delivered as a single self-contained HTML file at 1920×804, 24fps
