The texture uses granite and there is crand in the finish, but the variability
probably comes more from creating the shingles as isosurfaces and adding f_bumps
and f_snoise3d at different scales to the edges of the box.  Each shingle is an
individual object and is separately textured, so the textures get randomly
translated as well.
