Trevor Paglen, Trinity Cube (2015)
Irradiated broken glass collected from inside the Fukushima Exclusion Zone forms the outer layer of this sculpture. The work’s inner core is made out of Trinitite, the mineral created on July 16, 1945 when the United States exploded the world’s first atomic bomb near Alamogordo, New Mexico, heating the desert’s surface to the point where it turned surface sand into a greenish glass.
Trinity Cube was created by melting these two forms of glass together into a cube, then installing the cube back into the Fukushima Exclusion Zone as part of the Don’t Follow the Wind project. The artwork will be viewable by the public when the Exclusion Zone opens again, anytime between 3 and 30,000 years from the present.
