Building a circular model using LEGO is a challenge in itself, but Plastic Pauper took on that challenge and built a microscale city with not just one ring, but three, creating nested neighborhoods that all have a specific purpose and vibe. The outer ring looks industrial, with smokestacks, factories, and other gray structures. The middle ring is composed of many smaller buildings and greenery, while the central section sports tall, sterile, and modern structures fit for the city’s wealthy elite. And what futuristic city would be complete without flying cars?
