Hey, Hiro," the black-and-white guy says, "you want to try some Snow Crash?"
A lot of people hang around in front of The Black Sun saying weird things. You
ignore them. But this gets Hiro's attention.
Oddity the first: The guy knows Hiro's name. But people have ways of getting
that information. It's probably nothing.
The second: This sounds like an offer from a drug pusher. Which would be normal
in front of a Reality bar. But this is the Metaverse. And you can't sell drugs
in the Metaverse, because you can't get high by looking at something.
The third: The name of the drug. Hiro's never heard of a drug called Snow Crash
before. That's not unusual -- a thousand new drugs get invented each year, and
each of them sells under half a dozen brand names.
But a "snow crash" is computer lingo. It means a system crash -- a bug -- at
such a fundamental level that it frags the part of the computer that controls
the electron beam in the monitor, making it spray wildly across the screen,
turning the perfect gridwork of pixels into a gyrating blizzard. Hiro has seen
it happen a million times. But it's a very peculiar name for a drug.
The thing that really gets Hiro's attention is his confidence. He has an
utterly calm, stolid presence. It's like talking to an asteroid. Which would
be okay if he were doing something that made the tiniest little bit of sense.
Hiro's trying to read some clues in the guy's face, but the closer he looks, the
more his shifty black-and-white avatar seems to break up into jittering, hardedged
pixels. It's like putting his nose against the glass of a busted TV. It
makes his teeth hurt.
"Excuse me," Hiro says. "What did you say?
