A magnetic liquid-metal blob grows spiky protrusions that chase an orbiting magnet, driven by a live vertex-displacement field. Each frame, all 40,000+ vertices of a subdivided icosahedron are pushed outward proportional to their alignment with the magnet direction, raised to a power to create the classic sharp Rosensweig-instability spikes. Surface normals are recomputed every frame so the metallic clearcoat material reflects the changing geometry realistically.
