Tidal city made of glass. A city that rises and falls with the tides, buildings built on transparent platforms that reflect the ocean below. During high tide, the city floats, and water flows freely through its glass streets and plazas. During low tide, the city lowers into the sand, the glass structures glittering under the sun. Fish swim through the glass canals, and people walk along elevated pathways, the city reflecting the sky and sea, creating a shimmering, fluid environment.
