Voronoi Crystal Shatter

A glowing crystal cluster periodically shatters into irregular shards that explode outward, then reforms. The shard shapes are generated by sampling the faces of a subdivided icosahedron, an approximation of a 3D Voronoi diagram, the same partitioning concept used to model how mineral crystals, dried mud, and giraffe-skin patterns naturally split into irregular convex cells. Watch the intact crystal glow and slowly rotate, then explosively fracture along those cell boundaries with each shard tumbling outward under its own velocity and simulated gravity/drag, before the pieces reverse course and reassemble into the glowing core. The orbiting colored point lights and additive-blended sparkle field are there to emphasize the refractive, gem-like quality of the transmission material during each phase.
