A genetic engineer concocts a plan to transform a Galilean moon.

"Jonas is the conductor of a symphony, and must be familiar with each part, every section. He must keep them working in tandem, so he flits from group to group, giving encouragement. Visitors to the University wonder at the man skidding on the marble floors, running from A to E wing and back again. He reviews twenty sequences a day, though he is pleased to find few errors. His team works late. He works later. The key genes are reserved for his eyes alone, and when he sits back to watch the simulations play out he pictures the Watchmaker."

An "architectural fiction" centered around a city built by machines, for machines.

"Social spaces for machines bear the fragments of their tasks, and nothing superfluous. Machines don't need places to eat or sleep, but they need places for their own sorts of socially evocative maintenance rituals. They need places where auto parts can be partially assembled and taken apart, time and time again, like a game. Machines hang out in cafes while working on mundane maintenance tasks, with their component addresses made public in unique ways, so that other machines can gather together and show off their range of operations. Machines that build other machines take their half-finished constructions out in the company of other machines, so that they can build them together and get input on possible alternatives. There are public machine exercise spaces, where machines go through their range of motions and data abilities, for the purpose of showing off their various tolerances."
