 * This script adjusts the perspective of a CSS 3D transformed
 * box based on device orientation and motion. The box itself, 
 * including wall sizes, positions and rotation, is defined 
 * entirely in the main.css file and it's only the perspective 
 * that is changed via JavaScript.
 * 
 * Thanks to Nassim Benghmiss for adding orientation support.
