A radiolarian is a single cell that secretes a mineral cathedral around itself. Radiolaria Serena renders that skeleton at human scale in transparent polymer and light: a slow, continuous plasma that breathes through the lattice, the organism at rest. The light gives the microscopic architecture something it never had: visible emotion, here in its calmest state. Radiolaria Serena is part of NUR Living Lights’ research into Unseen Architectures, exploring hidden structures that connect the microscopic, the geological and the cosmic.
