"You make them by just pouring out some special imipolex, and that's that?"

"Of course not. In order to get any computational power, the little slugs of imipolex need to be doped with metals and seeded with chipmold. The main fab breaks that into numerous steps, but in here I have a nanomanipulator that can do everything at once."

Set into the back wall of the lab there was a three-dimensional nanomanipulator with a heads-up holographic display showing a magnified electron microscope image of the DIM inside it. The device also had a VR uvvy that allowed the user to fly about inside the image, using and programming the nanomanipulator's individual nanopincers and nanofeelers.

"It's fairly easy to train the nanomanipulator to do repeated steps," said Ramanujan. "If it was very much smarter, it would be a full-fledged moldie, and my security would be smashed to blazes. It's an awkward position I'm in.

Hopefully you can learn to emulate in some measure the efficiency of a moldie.

Go ahead and try on the uvvy."

Randy put it on. He was in an ocean of imipolex, with hollowed-out tube tu

"The metals and the spores have to be distributed in certain ways," said Ramanujan. "Fortunately, the controls are fractalized. That is, you can group them and cascade them. It's as if you could shrink your hands and put copies of your hands at the tips of each of your fingers—and then do it again."

Randy played around in the nanomanipulator's space for a while. The tubes were like pipes, and the cascaded controls were not unlike a multihead pipe-gun.

"I can drive this," he said presently. "But what patterns do you want me to put in?

Where are the specs?" "In here," said Ramanujan, tapping his head.

"How'm I go

"Just study the patterns I've been using and do something similar. As it happens, the actual pattern used for the etching process doesn't seem to be terrifically important. It's more like you're a farmer cultivating a field—you plow it up to a certain statistical density and then you broadcast your seeds.

The field and the seeds are smarter than the farmer."

"Thanks a lot, Sri. Now tell me about that other bench."

The biological bench along the left wall was covered with flasks and beakers where the chipmold cultures were prepared. One large beaker was half-filled with a gel of imipolex made cloudy by a million threads of mycelium. Up above the gel, great ruffs of chipmold climbed the sides of the beaker like shelf mushrooms on a rotten tree.

"That's one of the classic strains," said Ramanujan. "Each layer of my leech-DIMs gets a dusting of that fellow's spores. But the real computational power comes from the cultures in the flasks."

The flasks held agars of imipolex with chipmolds growing in them. Most of them held several kinds of mold, with the populations intermingling like plants in a meadow or like corals on a reef. In a few of the flasks, the regions of differently colored mold moved about at a visible pace, swirling like immiscible liquids.

Randy leaned over to stare deep into one of the little bottles and saw a background pattern of green-and-yellow citylike structures that were forever assembling themselves and breaking apart—geometric hives continually coming together and crumbling to pieces. Filling the spaces between the hives were lively vortex rings, each like a mushroom cap or like a jellyfish. These little jellyfish patterns were in shades of royal blue, tipped with vermilion accents.

They pulsed their way through the interstices of the background pattern, splitting in two at some intersections, merging at others. "It's pretty," said Randy.

"Yes yes," said Ramanujan. "Pretty complicated. Are you ready for me to go through the whole process for you step-by-step? I suppose we'll have to do this several times. Are you prepared to concentrate? Each full run-through takes about four hours."

"I'm ready," said Randy.

Over the following days, Ramanujan led Randy through the leech-DIM

fabrication process over and over until finally Randy could reliably do it himself. Randy was like a cook working for a master chef. As he grew more familiar with the recipe, he began finding ways to streamline it, although Ramanujan resisted any attempts to fully automate it. His great fear was that an automated process would amount to a program which could be stolen by Emperor Staghorn's industrial rivals, by the moldies, or by some other interested parties.

Such as the Heritagists. The evening after his first day of work with Ramanujan, Randy went to bed early. Parvati was feeling too weak to visit, and Randy was tired out from ru

Ramanujan was a slave driver. Just as Randy got into bed, his uvvy began beeping for him. Hoping it might be Parvati—he was eager to tell her that he'd nailed down the job—he slapped the uvvy on his neck.

"Hi there, Randy. You sure aren't very thoughtful about your old friends." It was a pale silly goose of a girl with a very bad complexion. For a moment Randy didn't recognize her.

"Helloooo! Salt Lake City calling Bangalore!" She waved both hands and gri

The whole dreary, smarmy, small-time-loser vibe of Heritagism came crashing back in on Randy. He'd completely blocked out Heritagism and the wretched Shively days since coming here—what with the interesting work at Emperor Staghorn, the fabulous love affair with Parvati, and the profoundly psychedelic camote visions to think about. Now and then he'd written his mother, sure, but he'd totally spaced out on his promise to make regular reports to the Je

"A little birdie told me you're moving up the ladder at Emperor Staghorn Beetle Larvae, Ltd.," said Je

"Uh, yeah, Je

"So?" Je

"So that's why I'm not too interested in talking to you."

Je

"I only started learnin' it today! Anyway, Ramanujan would kill me if he knowed I was leakin' on him. What the hell do you dooks have against moldies anyway?

They're beautiful!"

"Start uvvying me the information, Randy, or you'll find your Emperor Staghorn employee pass is void when you show up to work tomorrow. You'll be out of work and your little moldie girlfriend will rot to death. Believe it. Once a month I'm going to call you, and once a month you're going to run through the leech-DIM process for me. Each time you finish, I'll tell you which parts need more detail, and you'll get me the details by the next month. I'm not here to argue with you. I'm here to get the information."

So Randy told Je

That week the Emperor Staghorn Beetle Larvae company store let Randy get forty kilos of imipolex on credit, and Parvati was suddenly like new again. Shiva died right around then, and Parvati started living with Randy full-time, cooking and cleaning for him and flying him to and from work every day.
