GRAFFITI ART is known as one of the art jenre nowadays. A couple of decades ago,Soho or Harlem area of NYC is full of those graffiti paintings on the every walls of the old ruined buildings. Recently, those buildings have been renovated and reverse as a brand new,more stylish ones. There seems no space to scribble on anymore. Even if somebody prepared the wall to scribble for the graffiti artists, it's not exciting anymore. Actually, the real thrill of the scribbling is to paint something on the forbidden space!(but don't do that. it's against Law.)
