Street Tag for iPhone: Tag Up Walls with Graffiti Without Getting ArrestedCasey Chan8/08/11 6:53pm3EditPromoteDismissUndismissHideGo to permalink When I was young I associated graffiti with gangs and crime. Now that I'm older, it's probably my favorite form of art. I don't know my way around a can but I do know my iPhone. And with Street Tag, I can use my iPhone as a can of spray paint. SO FUN.
