Remember your first experience with the wonders of 3D cinema? You know, back when the 3D glasses you had to put on to enjoy the then-nascent technology had a lens in a different color from the other, and were ridiculously huge and made of cardboard? It was anything but wondrous, and that would be putting it mildly because so crude was the technology then that not a few people emerged from the 3D cinema experience nauseous, even physically ill.
