Cracking
Here the script to transform some subdivided parts to a sort of cracked mud.
The idea is to move the mesh differently if points are near the center of the exterior. The other trick is to connect the borders. Slider controlling the movement must be tuned to the size of the object. You will need Weavebird plugin.
I used here classical Voronoi, but you could use mesh clustering and other thessellation algorithms.
