Yep, sometimes graffiti can be pretty deep.

The graffiti in Spain is quite interesting. First off, like graffiti everywhere, the calligraphic style is similar - perhaps the medium dictates the look of the work. Secondly, there is very little "statement" graffiti, mostly words, possibly gang / artist names. Finally, there is almost no graphic graffiti - they will spray paint letters and words but not images. It is quite rare to find images.
