Inside, it was cool and bright, the chugging air-conditioners efficiently blasting purified air over the many work-surfaces. The barn was a good 25 feet tall, with a loft and a catwalk circling it halfway up. It was lined with metallic shelves stacked neatly with labeled boxes of parts scrounged from the junkyard. Perry set Elmo down on a workbench and worked a miniature USB cable into his chest-cavity. The other end terminated with a PDA with a small rubberized photovoltaic cell on the front. "This thing is running InstallParty -- it can recognize any hardware and build and install a Linux distro on it without human intervention. They used a ton of different suppliers for the BWE, so every one is a little different, depending on who was offering the cheapest parts the day it was built. InstallParty doesn't care, though: one-click and away it goes." The PDA was doing all kinds of funny dances on its screen, montages of playful photoshopping of public figures matted into historical fine art. "All done. Now, have a look -- this is a Linux computer with some of the most advanced robotics ever engineered. No sweatshop stuff, either, see this? The solder is too precise to be done by hand -- that's because it's from India. If it was from Cambodia, you'd see all kinds of wobble in the solder: that means that tiny, clever hands were used to create it, which means that somewhere in the device's karmic history, there's a sweatshop full of crippled children inhaling solder fumes until they keel over and are dumped in a ditch. This is the good stuff. "So we have this karmically clean robot with infinitely malleable computation and a bunch of robotic capabilities. I've turned these things into wall-climbing monkeys; I've modded them for a woman from the University of Miami at the Jackson Memorial who used their capability to ape human motions in physiotherapy programs with nerve-damage cases. But the best thing I've done with them so far is the Distributed Boogie Woogie Elmo Motor Vehicle Operation Cluster. Come on," he said, and took off deeper into the barn's depths. They came to a dusty, stripped-down Smart car, one of those tiny two-seat electric cars you could literally buy out of a vending machine in Europe. It was barely recognizable, having been reduced to its roll-cage, drive-train and control-panel. A gang of naked robot Elmos were piled into it. "Wake up boys, time for a demo!" Perry shouted, and they sat up and made canned, tinny Elmo "oh boy" noises, climbing into position on the pedals, around the wheel, and on the gear-tree.
