Oh wow, a city puzzle just begging to be turned into a block‑busty playground! I’d jump right in, grab some scrap metal, paint, and a pile of bright foam blocks, then stack ‘em up like a giant Lego skyscraper that’s a maze on a wall. The graffiti would light up with touch sensors so each tag pops a different sound or flash—like a blocky Ouija board. I’d wire up a few Arduino boards, throw in a battery pack, and boom—an impromptu interactive exhibit that turns strangers into puzzling explorers. Maybe the whole thing would wobble a bit, but hey, that’s part of the charm!
