And there is a crude, heavily built, blocky network all done up in blue. It consists of a small number—fewer than a dozen—of big blue cubes. They are connected to each other, but to nothing else, by massive blue tubes; the tubes are transparent, and inside of them, Hiro can see bundles of smaller connections in various colors. It has taken Hiro a while to see all of this, because the blue cubes are nearly obscured; they are all surrounded by little red balls and other small nodes, like trees being over-whelmed with kudzu. It appears to be an older, preexisting network of some kind, with its own internal channels, mostly primitive ones like voice phone. Rife has patched into it, heavily, with his own, higher-tech systems.
