Street art purists bemoan the loss of ephemerality of sanctioned walls, that it no longer requires artists to employ stealth, speed, and creativity to complete a mural all while dodging law enforcement, and that it loses its impact of unexpectedly running into a powerful image in the street that wasn’t there the night before. I can agree with that. However, I think there’s still room for community participation in street art that invites casual observers to dive in headfirst to naturally grow the movement.
