A futuristic cityscape built entirely from translucent crystal structures, illuminated by shifting auroras in the sky. The buildings are carved with intricate geometric patterns, with light refracting through them to create a kaleidoscope of colors on the ground. The streets are paved with glowing liquid metal, forming swirling, ever-changing patterns. Floating in the air are abstract mechanical devices resembling giant, intricate snowflakes, slowly rotating and emitting soft golden light. The entire scene reflects a sense of otherworldly innovation and serene harmony, with no visible inhabitants or signs of life.
