This paper introduces the methodology of a field work conducted in a public square in Barcelona, which gives significant weight to the observation and attentive ears of the urban environment to reflect and find the better manner to communicate the results of this ethnography. To be able to present the material gathered (field work’s notes but too, sounds recordings and photographies), digital technologies (such as Cd-rom or web page format) offered us alternatives to break the linearity of text on paper and playing with the various materials (text, image, sound) obtained. Move from paper to digital format requires a rethinking of strategies of writing usually used and, in the case of anthropology, these are still deeply rooted in literary traditions of the nineteenth century.
