From an ethnographic research and data gathered in this, a initiative came from us to create in Buenos Aires city, a theoretical and practical street art and graffiti workshop. In turn what happened in this, gave rise to another ethnography. There we put attention on the effects that the anthropological knowledge transfer occurs on the student by using pedagogically pictures and video. These effects can be noticed through the link between visual perception and culture. Otherwise, practical exercises of the workshop inspired us to think in a new way the relationship between public space, visuality and awareness.
