Olafur Eliasson, one of today's most acclaimed contemporary artists, and David Adjaye, a rising architecture star, have engaged in a unique collaboration. Eliasson's light installation "Your Black Horizon," which debuted at the 2005 Venice Biennale, was conceived from the start as a hybridization of both of their practices. The piece consists of a light, representing a horizon line, that emanates through a narrow gap in an architectural structure. This is the only light source, and it runs around the entire dark gallery space, without any visual obstruction. The optical illusion that is achieved is that of a reversed horizon line. This publication is presented in conjunction with the installation of this project in Croatia. Critic and curator Daniel Birnbaum, writer Eva Ebersberger and curator Daniela Zyman contribute in-depth essays, which are accompanied by large-scale spreads of the project.
