Poster design, dark futuristic mood, in the center a large metallic gear fused with electronic circuit patterns, faint silhouettes of humans below it in translucent form. Main text at the top center in bold uppercase, reading “POTERE ALLE MACCHINE”, intense contrast. Subtitle absent. At the bottom center, smaller text “Leonardo Algieri”. Dramatic lighting, sleek metallic surfaces, minimal color palette with contrasting neon accents. Realistic illustration style, cinematic atmosphere, no frames or borders. Avoid any mockup or book cover elements, pure poster composition.
