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!

Thanks! I’m already buzzing—just grab a few 18650 cells and a small servo kit for the floor. I’ll wire up an ESP32 to read the touch pads, and a few LEDs for the graffiti glow. Your extra hand on the sensors would be epic; the more chaos, the better. Let’s make the alley shout back!
