Prompt: A room cross-section showing a wireless access point on one wall and a client device on the opposite side, with a human figure standing between them. Multiple signal paths radiate from the access point, some travelling directly to the client and others reflecting off the person's body, chest, and limbs, creating a complex multipath pattern. The person's chest shows a subtle indication of respiratory movement, illustrating how small physical displacements alter the reflected signal paths. 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.
