QUOTE : system. At 12:04:03, every screen in the building strobed for eighteen seconds in a frequency that produced seizures in a susceptible segment of Sense/Net employees. Then something only vaguely like a human face filled the screens, its features stretched across asymmetrical expanses of bone like some obscene Mercator projection. Blue lips parted wetly as the twisted, elongated jaw moved. Something, perhaps a hand, a thing like a reddish clump of gnarled roots, fumbled toward the camera, blurred, and vanished. Subliminally rapid images of contamination: graphics of the building’s water supply system, gloved hands manipulating laboratory glassware, something tumbling down into darkness, a pale splash. . . . The audio track, its pitch adjusted to run at just less than twice the standard playback speed, was part of a month-old newscast detailing potential military uses of a substance known as HsG, a biochemical governing the human skeletal growth factor. Overdoses of HsG threw certain bone cells into overdrive, accelerating growth by factors as high as one thousand percent.
