Arup - Gyroscopic city scape rings

thingiverse

A two-piece round model was created with a 0.4mm gap between the top and bottom parts, allowing for smooth gyroscopic movement. The inner circle was hollowed out to make room for a randomly populated cityscape. To enhance realism, a window was added to one side of the inner circle, enabling viewers to see the city from various angles. Under direct sunlight, shadows cast by the buildings can be adjusted by rotating the inner circle.
