From the post

Jumping on the claude opus 5.5 one-shotting an explainer video bandwagon here... I went with @AnthropicAI 's own Constitutional AI paper, explained in 90 seconds 👇 Everything is code. Animation is Python + PIL, voice is Kokoro running locally, and the soundtrack is a D-major pad, arpeggio and kick built from raw sine and saw waves in numpy. It even caught and fixed its own bugs, like a font that dropped the crossbar on the "H". The best part is that every animation cue fires on the word being spoken, because it pulled word timestamps from the TTS. Change the script, re-run, and the whole thing re-times itself. @AmandaAskell @NotTomBrown
