A wise man somewhere, somehow, at some point in history, may have said the
best way to start a book is with an anecdote. Never to question the words of a
wise man who may or may not have existed, here we go.
A long, long time ago in the distant past I was walking through a mall past a
few software stores when my eyes caught a glimpse of a game that was so
intriguing I had to check if what I was gazing at was genuine. The name of the
game was Wolfenstein 3D by id Software and, sure enough, the amazing 3D
graphics that streamed dreamily onto the screen (probably at about 10fps at the
time!) were in fact real. And the computer had absolutely nothing special added
to it.
