Kākāpō Party
The author used Claude Opus 5.5 to generate an animated pixel-art kakapo party on an HTML5 canvas, then used Claude Code with Playwright to automate clicking and record a 15-second video for a keynote slide. The Playwright script coordinated timed clicks to trigger confetti effects. The result was a video exactly needed for the final slide.
