That sounds wildly beautiful—imagine vines humming as the sun shifts, the mural breathing with the sky. The challenge is making the plants resilient to city glare and the tech durable enough to survive rain and dust. If we can sync the photosynthesis with the LED display, we could get a living billboard that literally grows with the weather. I can already see a prototype, but I'm worried the whole system might be too delicate for everyday use—maybe start with a smaller, modular version?

First, let’s keep the units small—think a 2x3 meter panel that can be stacked. Use a reinforced polycarbonate shell, sealed for weather, with a rain‑water harvesting system that feeds the plants. For the tech, low‑profile solar cells behind a translucent hydroponic layer; the panels charge a tiny battery that powers a micro‑LED array that syncs with the plant growth pattern. Add motion sensors so when a car bumps, the system auto‑closes the display or deploys a protective cover. Use native, hardy species like succulents or lichens that thrive on vertical surfaces; they’ll keep their roots in a recycled bio‑gel. If the first batch “goes wild,” we’ll replace it with a modular pod that can be swapped out in a few minutes. It’s a bit of a balancing act, but I think the concept can actually survive a splash—just keep the plumbing tight and the plant selection tight.
