From 1996 until 2014, Eliasson collaborated with Icelandic artist and architect Einar Thorsteinn. ‘Model room’ contains a broad selection of the intricately constructed models, geometrical forms, and maquettes of various sizes that were developed by the two over the years. The artwork, which grew and changed as new studies were added, is shown here as it was installed at Louisiana Museum of Modern Art, Humlebæk, Denmark, in 2014. Thorsteinn, 1942–2015, an Icelandic mathematician and architect, was a close, long-term collaborator and friend of Eliasson and the studio.
