Hi @dswigle. That is very beautiful street art. I have seen graffiti before. And this art is nothing like that. I remember once reading about a project in some U.S. cities where graffiti is prevalent a program to give former graffiti enthusiasts a chance to create something beautiful...that is to paint over their graffiti with meaningful art, then sign it with their brand. What arose was the most beautiful art. And to my amazement, no other graffiti artist vandalized it or painted over it. So that was a worthwhile project.
I've also seen neighborhoods where the electric boxes on the street corners were painted, mostly with famous actors or just beautiful flowers to keep graffiti from being placed there.
