Voronoi ball

thingiverse

Humans are drawn to spherical objects that divide space into regions, each associated with a nearest point on the surface of the object. The most famous example is the Voronoi diagram, named after Georgy Fedoseevich Voronoy, who first described these partitions in 1908. When people see a Voronoi ball, they typically visualize a polyhedron that has been sliced open to reveal its internal structure, often with a complex web of lines and curves emanating from the surface of the object.
