I love complicated xtal shapes. These cubes are modified by a nice assortment of faces. The faces that parallel the edges of the cubes are not simple dodecahedral faces - there are two of them at a shallower angle than the dodecahedral face. I doubt any of the corner faces are octahedral - too many of them. (Author: Matt_Zukowski)
