The first time I saw 3D graphics was on my dad's computer when I was a boy. Dad was a programmer for the phone company, back before they called programmers "coders" and before being a coder was cool. He didn't make apps; he wrote routines for a brute of a mainframe that lived somewhere in the bowels of Pacific Bell. He stayed up all hours of the night telecommuting before it was a perk of every job. Sometimes, my younger brother and I would wander in to see what he was up to, and if we were lucky, he'd set us on his lap and boot up a game, Wolfenstein 3D, a first-person shooter. You were a GI trying to escape a Nazi castle.
