I don't think inkscape has that. Looks like the POV-ray pattern 'Crackle':

--clip-- 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).

By the way, this might make a useful Python effect for Inkscape: Fill the inside of a path with random points and build a Voronoi diagram (as a set of polygon paths) of these points, or of the path's nodes, or both. Any takers?
