I never really take time with graffiti when I see it because I don't usually like the style even though I'm mesmerized by the skill required to do it. In Chile, the graffiti is painted with brushes which makes me smile because under cover of night, some kid is painting stylized letters with a brush and a can of paint, lots of cans of paint, and waiting, waiting, waiting for it to dry so he can do the next layer. It must take all night.
