The antiAtlas of Borders is an experimentation at the crossroads of research, art and practice. It was launched in 2011 at the Mediterranean Institute of Advanced Studies (Aix Marseille University), and has been co-produced by the Higher School of Art (Aix en Provence), PACTE laboratory (University of Grenoble-CNRS), Isabelle Arvers and La compagnie. Since then, it has gathered researchers (social and hard scientists), artists (web artists, tactical geographers, hackers, filmmakers, etc.) and professionals (customs, industry, military, etc.). The encounter of people coming from these different fields of knowledge and practice aims to create a radical shift of perspective in the way we apprehend both 21stcentury borders and the boundaries separating fields of knowledge, art and practice.
