14. The Astral Data Pillar
Reaching into the upper atmosphere, the Astral Data Pillar acts as the primary communication array for your futuristic world. The structure relies heavily on vertical lines, utilizing polished White Quartz Pillars, Dark Oak Wood, and Tinted Glass to create a slender, elegant frame. The centerpiece of the building is a giant, hollow core containing floating, rotating ring segments built from Gold Blocks, Sea Lanterns, and Cyan Stained Glass. These segments simulate an intricate quantum computing core transferring petabytes of data directly to satellites in orbit, illuminating the clouds above with bright blue and gold neon rays.
