A full-bleed underwater backdrop modelled on brinicles: dense, sub-zero brine sinking off newly formed sea ice freezes a hollow ice sheath around itself as it descends, flashes an expanding freeze halo where it touches bottom, then breaks free and drifts off while a fresh tip nucleates elsewhere. Several overlapping lifecycles running at once so the pane is never empty.
