#### Crackle

The `crackle` pattern is a set of random tiled polygons. With a large scale and no turbulence it makes a pretty good stone wall or floor. With a small scale and no turbulence it makes a pretty good crackle ceramic glaze. Using high turbulence it makes a good marble that avoids the problem of apparent parallel layers in traditional marble.

Mathematically, the set crackle(p)=0 is a 3D Voronoi diagram of a field of semi random points and crackle(p) < 0 is the distance from the set along the shortest path (a Voronoi diagram is the locus of points equidistant from their two nearest neighbors from a set of disjoint points, like the membranes in suds are to the centers of the bubbles).
