In this video, Maëva Longvert, founder and stage director of Le Polymorphe, describes a scale of disturbance that she uses in her co-existence with people on the sites in which she works. She explains the importance of taking into account the environments in which she works, through the Nyctalope project on the role of women in public space, and in her “En vol” project, with the close relationships she builds through with the life stories of the people she meets.
