The project emerged from a personal experience, teaching art classes in a marginal area, where the majority of the children had the example of following criminals, gang members, police men and evangelical priests. Confronted with this situation, I asked myself about the true utility of my work, as when finished, poverty, the school’s desertion and violence continued. “Arar en el mar” suddenly made sense to me and I considered this expression not only to include myself, but also many other people that work every day without questioning if their work has an objective, castillos in the air.
