This film shows how to assemble the components of the ‘Green light’ lamp into a completed module. Initiated by Eliasson in collaboration with Thyssen-Bornemisza Art Contemporary (TBA21) in Vienna, Austria, in 2016, ‘Green light – An artistic workshop’ is a response to the current geopolitical situation in which millions of people have been uprooted by war and violence as well as to broader issues surrounding global migration. It shines a metaphoric green light to asylum seekers, refugees, and economic migrants by inviting them to participate in a multi-faceted program of creativity and shared learning. This includes a workshop for the construction of ‘Green light’ lamps, as well as language courses, seminars, artist’s interventions, and film screenings.
