Green light, the Vienna-based art project launched by Olafur Eliasson to welcome refugees, is coming to Art Basel this weekend. Since March, participants from countries including Syria, Afghanistan and Iraq have worked with local people at Thyssen-Bornemisza Art Contemporary to make nearly 300 green lamps designed by the Danish-Icelandic artist. Participants will present the project inside Oscar Tuazon’s wooden structure on the Messeplatz, on 18 and 19 June. Lamps will be available for SFr350 each. Proceeds go to projects that help refugees. Green light is due to continue in Vienna during June and July.
