Coal memorial. A wall is covered by 175 silkscreened black‑and‑white portraits of Palestinians killed by the Israeli army at the beginning of the second Intifada, their faces, barely discernible and ghostly – physically lost, their identities not officially recognised. They only take shape as the visitor moves around them in space, appearing and then disappearing before their eyes in accordance with the luminous shimmering on their surface. (text by Sophie Jaulmes)
