The resulting visualization can be sequence together into an animated series using the grass SG3D program (Figure 4: SG3d.final.gif):

After having created a database of interest, one can do manipulations that correspond to typical GRASS usage. If you are interested in the geology of the terrain, you might want to obtain a Mapset that has coloration indicative of the terrain type, as well as a classification of the elevations of a certain steepness. This usage correspond with the workshop example mentioned previously (and supplied in Section 1.5.1 : Stanford Workshop Grass Tutorial).
