Street art often gets dismissed as vandalism, but I've seen it transform neglected neighborhoods into cultural hotspots. In places like Melbourne, guided tours now bring thousands of visitors to laneways that were once just back alleys. My own city has a mural festival every year, and the area around it has seen new cafés and shops open up. Could this kind of public art actually be a legitimate form of urban development, or is it still just graffiti with a marketing spin?
