There may be no better portrayal of the survivor’s vision faced with a thread of hope than Perpetual Repercussion, the work of artist Dyveke Sanne that envelops the façade of the Seed Vault. Like a halo, its cleverly arranged reflective steel triangles capture the Arctic light and cast it far onto the pristine white snow. Its appearance changes depending on the time and the season. At night, for example, it glows in the dark using a fibre-optic light system. Just like this earring.
