For the past five years the REITIR team has been running an annual two-week experimental workshop in Siglufjörður. The workshop is about collaboration, site-awareness, cross-disciplinary tools, social engagement and interventions in public space. It’s known as the REITIR workshop, but there is more to it than that. Two members from the team, Arnar Ómarsson and Ari Marteinsson had a discussion about the project and the publication of the book Tools For Transformation wich is based on the methodes used at the workshop.
