  The plaza in front of the Shaft One station was less crowded than the
lochoi interchange had been, despite the expensive shops and the
info-vendor's massive newswall.  Jian glanced from side to side, sampling
the projected glyphs.  The police code, flaring hot red and brighter than
all the other symbols, startled her into a second look, to see the floater
grounded outside a Salli's, the two cops, Cartel Security rather than the
Freyan Provisional Government's police, sitting compionably on the running
board eating noodles out of self-heating cups.  The floater's ID light was
running, throwing red and blue lights across the plaza and broadcasting its
glyph into the virtual world.  There was still no word of Libra, nor had 
she really expected it. 
  The display board above the station's entrance flashed twice, drawing her
eye, then spat a stream of glyphs and numbers.  The suit supplemented
that with further annotation, clusters of smaller symbols floating in
virtual space between her and the sign.  The next three cars would be
running express to the Li Po Township Station -- shift change, she
thought, and was briefly annoyed at having forgotten -- and regular
service would resume in twenty minutes.  Li Po was too far out of her
way, would mean doubling back up through the local shafts before she could
take the electrobus along the Zodiac.  Better to wait, and go direct.
  She crossed the plaza then, glancing almost idly at the info-vendor.
Triggered by her suit's interrogative signal, the newswall blossomed to
life, offering a montage of film and glyphs, accompanied by a smaller
realprint crawl.  She paused -- like most of the city's population, she got
her news from the walls' free teaser displays, rather than paying the fees
either to subscribe to a service or even to view the more comprehensive
reports the vendors sold -- and the wall steadied into its summary.  Glyphs
highlighted the moving pictures, identifying the figures in their severe
corporate silks, while the crawl updated the latest conference between the
Staryards Cartel that managed the planet and the Freyan Porvisional
Government that actually owned the world....
