Substorm Sea

A complex fractal pattern of flowing, vertical lines of light. The colour transitions from deep, dark purples at the top to vibrant, glowing blues and neon greens near the horizontal axis. The composition resembles a magnetic field, with symmetrical structures rising from a central line. The Burning Ship map z -> (|Re z| + i|Im z|)² + c iterated over the parameter plane. The colour bands run along the equipotentials and the curtains of light follow the field lines.
