For those otherwise unaware, I've made my living working in the computer gaming industry primarily as a 3D graphics programmer--responsible for the code that takes those "wireframe" objects you see that were designed by artists and draws them properly in the right place given where the "camera is", and lights and shades them to look realistic. I'm also, as a player, particularly a fan of the "first person POV" game, where the camera is the eyes of a virtual character in the world.
The irony is, I'm also one of those people who gets motion sickness from these kinds of games.
(I didn't used to, but once 3D graphics hardware raised the quality and especially the frame rate of the images, it started happening. I first encountered it, as I recall, playing Half-Life.)
