Claude Opus 5.5 makes a Blender short film about the last black hole — 3,000 lines of Python, no gen models

Given just an idea (the last black hole evaporating) and two editing notes, Claude Opus 5.5 produced a short film entirely in code — no image or video generators. It wrote 3,000 lines of Python to build and render the office set in Blender, with each light rendered separately so lamps can flicker and die; it composed original music via its own synthesizer and used the open-source Kokoro TTS locally for voice. The physics is real: the countdown drops a power of ten per tick from 10^100 years, the rising tone follows the actual Hawking temperature curve, and terminal numbers show real mass and temperature. It even self-checked the audio mix with loudness measurements, spectrograms, and speech recognition. First cut took under two hours, about one spent rendering.
