City of Sao Pulo recently introduced the law of ‘visual pollution’ banning billboards from the streets. It was discussed that every billboard can distract driver for 15 meters, causing great risks in traffic.
So, what is other place where lots of people travel and have enough time to consume commercials? Well, its metro. Metro cars have small screens with non stop video commercials.
Here you can also here an audio drive-trough one of the stations of LINHA VERDE (green line) at Sao Paulo metro.

Many thanks to all participants an special tenks to Giuliano Obici and Alexandre Freire that made this workshop possible.
On Thursday 05/04/07 an event has been organized by Drica Velose, Gastao Frota, Junia May Teixeira, Tanja Topolovec and Kruno Jost. Event was a collaborative work that included multimedia installation, audio and stage set, with digital visualization including feedback image.
During the evening some of the visitors followed Gastaos performance influence and started interacting with the visualization and stage set. In the atmosphere similar to Fluxus event, with naturally inborn feeling for interacting with the surrounding and taking part in action, visitors were discussing, reacting, taking part and helping with ongoing changes of the event.
Alexandre Freire, one of the participants on the Upgrade!Salvador gives a 10 minute insight into history and preasent of the workgroup des).(centro.
During lat week of March 2007. a meeting was held in Salvador, Bahia. DesCentro members have met in order to make a firm base (functional as well as legislative) on further development of this network.
DesCentro is de-centralized organizational node of collaborative actions, inserted in broader context of Brazilian media activism. This context is formed by group of organizations, researchers, activists, teachers, hackers and artists coming from all regions of the country. More details on DesCentro.
Main DesCentro’s goal is to develop the methodological structural and approach to optimize network that has been working together for more than five years, avoiding the downsides of common institutionalization. Even the way DesCentro was established is deep criticism to the well-known NGO “show business”. Another situation DesCentro intends to provide is ways for people to carry out independent research and practice and still earn for their living, respecting the principles of collaboration, de-centralization, diversity and freedom.
History of DesCentro has been a collective work of different groups and collectives. Through meetings and online contacts good conections were established inside Brazil as well as in the world, mainly India and Netherlands. Members took part in events such as Media Tactica Brasil, Next5Minutes4 in Amsterdam, Alternative Law Forum and Submidialogia.
In October 2005. Submidialogia happened in Campinas, Brazil. A group formed by members of Metareciclagem, Tactical Media and SubmÃdia emerged and decided to work together within the perspective of developing an organizing node for the Brazilian critical media networks, in to order to promote the development of tactical media exchange and projects.
