# Obsidian Spine Helix

A near-black obsidian double helix wound around a bright axial filament, turning once per loop with every edge rim-lit. Each vertebra is one bead-and-process primitive under seven interpolated numbers, so it morphs by deforming, not cross-fading, through four forms: stacked plate, processed vertebra, swept barb, radiating quill. Bass widens the helix, mid twists it, treble ignites the rims, and the change climbs the spine. Rests as the processed vertebra.
