 * This is an example of using the accelerometer to integrate the device's
 * acceleration to a position using the Verlet method. This is illustrated with
 * a very simple particle system comprised of a few iron balls freely moving on
 * an inclined wooden table. The inclination of the virtual table is controlled
 * by the device's accelerometer.
