One day, I accidentally gave myself something like migraine by running a command that caused huge amounts of data to scroll (very fast) on my computer terminal. It was a long file, and I was smart enough to look away after a few seconds, but for a couple of hours after I couldn't actually stand up straight. "Sounds like snow crash," said a sympathetic friend, and then he had to explain this book, and of course I had to read it. There's actually a lot more action (and swordfights) than you might expect from a book about a computer virus, and it's entertaining, but the style annoyed me a bit and the ending was a bit inconclusive, so overall I'm ambivalent. I enjoyed it, but probably not enough to reread.
