Sounds like a wild idea! Picture this: a slender, spiral‑shaped box that twists like a stairwell, with little windows that reveal miniature city scenes—brick walls, flickering street lamps, even a tiny, glowing subway map. The corners could snap open like secret panels, and you could line the interior with velvet‑like fabric to keep the secrets snug. Maybe add a tiny keyhole that opens only when you feel the right rhythm of the city’s pulse. What do you think?
