A clockwork bird comes to life in a 60-second short

From the post

🚨Fable 5.5 TESTING I typed ONE sentence into Claude Code 1 hour 54 minutes later, it handed me this: a 60-second short film about a clockwork bird coming to life. 🐦⚙️✨ Art, animation, music AND sound effects, all made by an AI agent. No stock footage. No sound library. 🤯 Here's what it actually did 👇 🎨 THE ART • Drew the bird itself from scratch as cel-shaded vector art, so every gear, spring and feather is its own piece that flies in and lands 🎬 THE SHOT • One continuous camera move: from the hill, through the open attic window, down to the bench, and out into the clouds ☁️ • A gust of wind carries brass parts in, and they click together one by one • Then the bird WAKES UP 👁️ Its eye kindles. It blinks. Tilts its head. Shakes off the dust. Stretches its wings. Hops. Looks at the window… • …and flies. 🕊️ 🎻 THE MUSIC • An original waltz, written as code, note by note • One melody travels the whole film: flute on the hill → celesta in the attic → oboe as the wings go on → violins as the key winds up → full orchestra as it bursts into daylight • The clockwork's ticking lands exactly on the beat ⏱️ 🔊 THE SOUND • Every effect was synthesized from pure math: metal clicks, gears seating, wind, fluttering curtains, wingbeats, swallows outside • Each click is synced to the exact frame the part touches, within 5 milliseconds 🎯 💸 THE COST ⏳ 1h 54m from prompt to finished MP4 💰 About $20 in API costs 🙋 My input: one sentence Built with Claude Code + HyperFrames (HTML → video) Sound ON 🔊👇

Make me an animated video of a mechanical bird getting assembled and flying away
