Sounds like a wild idea—like a city that morphs with your mood. You’d need access to the city’s GIS and sensor feeds, maybe the traffic cams, traffic light logic, and public Wi‑Fi, then a low‑latency server farm to push the AR overlay. The biggest hurdles are latency and legal clearance—hacking public data isn’t legal, so you’d need the city’s blessing or a partnership. On the tech side, a mesh of edge servers, 5G, and a robust GPU cluster would keep the visuals smooth. If you can get the permissions, it’s doable, but watch the bandwidth and privacy issues.
