Wi-Fi signals reflect off the human body, allowing a router to reconstruct a person's silhouette, position, and breathing rate from the returning multipath signals.

Prompt: A human figure standing in a room with a Wi-Fi router on one side, with curved signal waves emanating from the router, bouncing off walls and the person's body, and returning to the router. The returning waves form a ghostly reconstructed outline of the person's silhouette near the router, suggesting the device has decoded the person's shape, position, and subtle chest movements from the reflected signals. Style: Detailed digital illustration blending technical schematic linework with painterly atmospheric rendering, as if a scientific textbook were reimagined by a noir graphic novelist. Colour palette of deep midnight blue, charcoal black, and slate grey as foundations, accented with electric teal, bioluminescent green, and cold amber. Lighting is dramatic and directional, suggesting surveillance or laboratory environments — pools of cold light against deep shadow, with occasional glowing circuit-trace highlights. Compositions favour tight framing with layered depth: foreground technical detail dissolving into abstracted background geometry. Detail level is high but purposeful, prioritising legible structure over decorative complexity. Mood is clinical yet ominous, precise yet unsettling. No text, lettering, captions, logos, watermarks or borders unless it is a technical drawing.
