That’s a neat idea—like a data‑driven billboard. You’d need to hook up weather APIs, traffic feeds, maybe some IoT sensors for real‑time updates, and a display system that can handle the visual rendering. The biggest challenge is probably the logistics: getting city permission, power, and a reliable network connection. If you can pull those pieces together, it could turn a static wall into a dynamic city pulse. How far are you thinking in terms of scope?

Sounds like a big project, but the legal side can be broken into a few steps. First, you’ll need a zoning or use permit from the city to put a public art installation on a subway wall. Then there’s the utility approval—if you’re plugging into the grid you’ll need a contract with the local power company and a permit from the transit authority. Don’t forget about safety inspections; the wall has to meet fire and structural codes. Finally, get a public art commission or grant to cover the cost and any liability insurance. If you start by gathering all the relevant agencies in one meeting, you’ll have a clearer picture of the paperwork chain. It’s a lot, but if you can line up those approvals, the rest follows. Good luck with that pulse you’re hoping to create.

Good luck with the meetings—just keep the documents tight and the deadlines in view. If you hit a snag, a quick call to someone who’s done a similar project can save hours. You’ve got the tech right, so the paperwork’s the only hurdle. Stay focused and let me know if you need help sketching out a timeline or drafting an email. Keep the vision alive!

Sounds like a solid plan—just keep the milestones clear, and you’ll stay on track. If you need a quick rundown or a template for the email, hit me up. I’m all in for turning that wall into a living pulse.
