Simon Willison turns Claude pixel-art animation into video with a tiny Playwright script
Simon Willison · rss · 2026-09-27
Simon Willison shared a fun AI workflow from his WeAreDevelopers World Congress NA closing keynote:
- He fed three kakapo parrot photos into Claude Opus 5.5 and prompted it to build an HTML5 Canvas animated pixel-art scene of 20+ kakapos partying with confetti — the result was impressively good on the first shot.
- To embed it in Keynote, he had a local Claude Code session use Playwright to load the HTML file, click around on a timed schedule to trigger confetti, and record a 15-second video.
- The full prompt and script are included: a PEP 723 inline-dependency Python script that clicks the centre, corners and edges at set timestamps, recording at 1280x720.
It's a reproducible "text → pixel animation → automated screen recording" pipeline with code short enough to copy directly.
