This is an early Eighties revisitation to the idea in
Caliban: future humans are able to change their bodily appearance as the fancy takes them. In this case, the procedure is only available to a privileged class of the super-rich, while the standard underclass is left to their natural forms. The conglomeroid class prefer wildly imaginative shapes: geometric constructs, incongruous mixtures of different animal characteristics. The only constraint is that the body must house a human brain. Worldwide transportation is quick and easy to the overclass, and the favored style of housing seems to be egg-shaped and off the ground. See the cover art to The Conglomeroid Cocktail Party for an idea (but ignore the hatching triceratops, they're in
Our Lady of the Sauropods).
