From Wolfram: "Escher's solid" is the solid illustrated on the right pedestal in M. C. Escher's Waterfall woodcut (Bool et al. 1982, p. 323). It is obtained by cumulating a rhombic dodecahedron until incident edges become parallel, corresponding to a cumulation height of sqrt(2/3) for a rhombic dodecahedron with unit edge lengths. It is the first rhombic dodecahedron stellation and is a space-filling polyhedron. Its convex hull is a cuboctahedron.
