Indicación de lapso de tiempo de evolución de la ciudad

Start with a quiet dawn beside a calm river: soft mist hangs low, birds drift across the water. A solitary wooden hut stands by the shore - primitive, handmade, smoke curling from its chimney. As time accelerates, the hut splits and multiplies into other small dwellings - then shifts to stone and brick. Roads emerge like veins in all directions, horse-drawn carts flickering into motion. In a heartbeat, buildings grow taller - brick becomes steel, then glass. Horse carts vanish into early automobiles, which blur into electric trams, then vanish again into ghosted traces of traffic. Skyscrapers rise in rhythmic bursts, each floor stacking faster than the last. Streetlights blink to life, glowing yellow then cool white, as day shifts to night and back in rapid cycles. The skyline thickens, cranes swing and dissolve mid-build, neon signs and digital screens flicker on. The city pulses with life - people as blurred streaks, windows as glowing cells in a living organism. End with a sweeping aerial view: a gleaming modern metropolis, riverside still visible, where only silence lived ten seconds ago.
