Miniature City Timelapse Inside Light Bulb

15-second cinematic fantasy timelapse short. No humans. No text, no logo, no watermark. A broken old light bulb sits on a dark tabletop. The camera starts with an extreme close-up of the cracked glass and broken filament. Tiny electric sparks flash inside the bulb, glowing dust spins rapidly, and the camera makes a fast push-in as if entering the glass world. Inside the bulb, a miniature city forms in a dynamic timelapse. Tiny roads shoot outward like glowing veins, small bridges assemble, buildings rise quickly from particles, rooftops pop into shape, and narrow streets connect at high speed. Use energetic but clear motion, not slow magical drifting. The camera cuts between macro close-ups of tiny buildings growing, a fast overhead-like view through the curved bulb glass, and a dramatic side angle showing the whole city expanding inside the bulb. Make the formation feel satisfying and fast, like a tiny civilization being built in seconds. In the final part, the city suddenly comes alive. Windows light up one after another in a rapid chain reaction, streetlights flicker on, tiny moving light trails suggest life in the streets, and the entire bulb glows warmly from within. The camera pulls back quickly, then settles into a beautiful lingering hero shot of the broken bulb containing a fully illuminated miniature city. The ending should feel magical, cinematic, and complete, but the middle must feel fast, active, and visually dynamic. Magical realism, detailed miniature city, warm amber light, glass reflections, high contrast cinematic lighting. No background music. Sound effects only: sharp electric crackles, tiny construction-like clicks, rising sparkling sounds, glass resonance, soft final electric hum.
