Last fall, a group of URBANlab architecture students from the California College of the Arts, Rebar art and design studio, and Landscape David Fletcher started their assignment adventure a a local taco truck. The research, based on SF's food and watersheds, was based on the premise that the familiar food (aka tacos) are part of a greater subliminal system and could give visceral insight to other connections in the environment. Similar to the work by Sourcemap, awareness of your input (and hopefully output one day) helps the user to see their own connection and potential impact to those around them and the environment.
The work is being presented this Thursday, Feb 25 in the Mission in San Francisco.
This week I will try to make a project similar to this but with ranges.
