Graffiti Flix
Since 'Graffiti Art' art is so cenytral to the story, there's attempts within the book to portray the graffiti as reaslistic as possible. And that tends to mean, most of it wasn't very good. The majority of stuff we painted during my adolescent years was decent to pretty bad. 

But as they say, you only start getting good at graffiti at about the age when you should really start thinking about quitting!
