Photograph a hyper-clean, futuristic cityscape dominated by sleek white buildings with reflective surfaces that shimmer with holographic displays. Tiny nanobot swarms flit through the air, forming delicate patterns of light and motion. Transparent walkways connect buildings, while automated vehicles glide silently along the streets. The sterile, glowing environment is bathed in a faint, bluish light that accentuates the precision and micro-scale detail of the nanotechnology.
