The poster for the tech conference on Smart Cities offers a vision that closely aligns with the original coastal cityscape, enriched with modern smart city elements. The high-angle perspective captures a mixture of contemporary and older buildings, subtly enhanced with advanced features such as solar panels, green rooftops, and smart lighting. The prominent white circular building in the foreground now boasts high-tech accents, blending seamlessly into the urban environment. The city extends towards a harbor where traditional ships mingle with a few autonomous vehicles, maintaining the essence of a vibrant coastal metropolis.
