Well, one more then. Experimenting with polyspheres for rocks, and this came out. So the base is an octahedron with an image map for its displacement. Then a population of mesh-modified polyspheres projected from above. The eyes are just voronoi (red node) noise based. Only the veins in the eyes are from blue node voronoi. The eyes are subsurface scattered through a glass shader, the rest is not.
The hanging mosses pop are projected from below onto the octahedron.
And some stuff to make it funny.
