This paper summarizes some recent progress in our understanding of the morphological diversity of dust comets. This diversity is a product of dust emission from discrete active areas on the nucleus surface and provides information on the comet's rotation state and source function. Advances in computer simulations of large-scale dust coma morphology are described and the diagnostic properties of various dusty features are emphasized. Also addressed are some of the issues of dust tail morphology and particle fragmentation. Finally, constraints on the mass, size, and velocity field of the dust population of comet Shoemaker-Levy 9 are set from the object's morphological observations in 1993-94.
