That's what's happening today, Nell. Mites fighting other mites. This dust– we call it toner– is actually the dead bodies of all those mites."

"When will the war be over?" Nell asked, but Harv could not hear her, having entered into another coughing jag.

Eventually Harv got up and tied a strip of white Nanobar around his face. The spot over his mouth immediately began turning gray. He ejected used cartridges from his mite gun and inserted new ones. It was shaped like a gun, but it sucked air in instead of shooting things out. You loaded it with drum-shaped cartridges filled with accordion-pleated paper. When you turned it on, it made a little whooshing noise as it sucked air– and hopefully mites– through the paper. The mites got stuck in there. "Gotta go," he said, goosing the trigger on the gun a couple of times. "Never know what I might find." Then he headed for the exit, leaving black toner footprints on the floor, which were scoured away by the swirling air currents in his wake, as if he had never passed that way.

Bespoke was a Victorian house on a hill, a block long and replete with wings, turrets, atria, and breezy verandas. Hackworth was not senior enough to merit a turret or a balcony, but he did have a view into a garden where gardenia and boxwood grew. Sitting at his desk, he could not see the garden, but he could smell it, especially when the wind blew in from the sea.

Runcible was sitting on his desk in the form of a stack of papers, most of them signed JOHN PERCIVAL HACKWORTH.

He unfolded Cotton's document. It was still running the little industrial cartoon. Cotton had clearly enjoyed himself. No one ever got fired for going with enhanced photorealism, but Hackworth's own signature look was lifted from nineteenth-century patent applications: black on white, shades of gray implied with nearly microscopic crosshatching, old-fashioned letterpress font a little rough around the edges. It drove clients wild– they always wanted to blow up the diagrams on their drawing-room mediatrons. Cotton got it. He'd done his diagram in the same style, and so his nanotechnological battery chugged away on the page looking much like the gear train of an Edwardian dreadnought.

Hackworth put Cotton's document atop the Runcible stack and guillotined it against the desktop a couple of times, superstitiously trying to make it look neat. He carried it to the corner of his office, over by the window, where a new piece of furniture had recently been rolled in by the porter: a cherrywood cabinet on brass casters. It came up to his waist. On top was a polished brass mechanism– an automatic document reader with detachable tray. A small door in the back betrayed a Feed port, one centimeter, typical of household appliances but startlingly wimpy in a heavy industrial works, especially considering that this cabinet contained one of the most powerful computers on earth– five cc's of Bespoke rod logic. It used about a hundred thousand watts of power, which came in over the superconducting part of the Feed. The power had to be dissipated, or else the computer would incinerate itself and most of the building too. Getting rid of that energy had been much more of an engineering job than the rod logic. The latest Feed protocol had a solution built in: a device could now pull ice off the Feed, one microscopic chunk at a time, and output warm water.

Hackworth put the stack of documents into the feed tray on top and told the machine to compile Runcible. There was a card-shuffling buzz as the reader grabbed the edge of each page momentarily and extracted its contents. The flexible Feed line, which ran from the wall into the back of the cabinet, jerked and stiffened orgasmically as the computer's works sucked in a tremendous jolt of hypersonic ice and shot back warm water. A fresh sheet of paper appeared in the cabinet's output tray.

The top of the document read, "RUNCIBLE VERSION 1.0– COMPILED SPECIFICATION." The only other thing on the document was a picture of the final product, nicely rendered in Hackworth's signature pseudo-engraved style. It looked exactly like a book.

On his way down the vast helical stair in the largest and most central of Bespoke's atria, Hackworth pondered his upcoming crime. It was entirely too late to go back now. It flustered him that he had unconsciously made up his mind months ago without marking the occasion.

Though Bespoke was a design rather than a production house, it had its own matter compilers, including a couple of fairly big ones, a hundred cubic meters. Hackworth had reserved a more modest desktop model, one-tenth of a cubic meter. Use of these compilers had to be logged, so he identified himself and the project first. Then the machine accepted the edge of the document.

Hackworth told the matter compiler to begin immediately, and then looked through a transparent wall of solid diamond into the eutactic environment.

The universe was a disorderly mess, the only interesting bits being the organized anomalies. Hackworth had once taken his family out rowing on the pond in the park, and the ends of the yellow oars spun off compact vortices, and Fiona, who had taught herself the physics of liquids through numerous experimental beverage spills and in the bathtub, demanded an explanation for these holes in water. She leaned over the gunwhale, Gwendolyn holding the sash of her dress, and felt those vortices with her hands, wanting to understand them. The rest of the pond, simply water in no particular order, was uninteresting.

We ignore the blackness of outer space and pay attention to the stars, especially if they seem to order themselves into constellations. "Common as the air" meant something worthless, but Hackworth knew that every breath of air that Fiona drew, lying in her little bed at night, just a silver glow in the moonlight, was used by her body to make skin and hair and bones. The air became Fiona, and deserving– no, demanding– of love. Ordering matter was the sole endeavor of Life, whether it was a jumble of self-replicating molecules in the primordial ocean, or a steam-powered English mill turning weeds into clothing, or Fiona lying in her bed turning air into Fiona.

A leaf of paper was about a hundred thousand nanometers thick; a third of a million atoms could fit into this span. Smart paper consisted of a network of infinitesimal computers sandwiched between mediatrons. A mediation was a thing that could change its color from place to place; two of them accounted for about two-thirds of the paper's thickness, leaving an internal gap wide enough to contain structures a hundred thousand atoms wide.

Light and air could easily penetrate to this point, so the works were contained within vacuoles– airless buckminsterfullerene shells overlaid with a reflective aluminum layer so that they would not implode en masse whenever the page was exposed to sunlight. The interiors of the buckyballs, then, constituted something close to a eutactic environment. Here resided the rod logic that made the paper smart. Each of these spherical computers was linked to its four neighbors, north-east-southwest, by a bundle of flexible pushrods running down a flexible, evacuated buckytube, so that the page as a whole constituted a parallel computer made up of about a billion separate processors. The individual processors weren't especially smart or fast and were so susceptible to the elements that typically only a small fraction of them were working, but even with those limitations the smart paper still constituted, among other things, a powerful graphical computer.

And still, Hackworth reflected, it had nothing on Runcible, whose pages were thicker and more densely packed with computational machinery, each sheet folded four times into a sixteen-page signature, thirty-two signatures brought together in a spine that, in addition to keeping the book from falling apart, functioned as an enormous switching system and database. It was made to be robust, but it still had to be born in the eutactic womb, a solid diamond vacuum chamber housing a start matter compiler. The diamond was doped with something that let only red light pass through; standard engineering practice eschewed any molecular bonds that were tenuous enough to be broken by those lazy red photons, underachievers of the visible spectrum. Thus the growth of your prototype was visible through the window– a good last-ditch safety measure. If your code was buggy and your project grew too large, threatening to shatter the walls of the chamber, you could always shut it down via the ludicrously low-tech expedient of shutting off the Feed line.
