Code :)

// It will render, as a 3D box, the angle of the accelerometer.

  int x, foobar, z // Create the variables for the values from the accelerometer

  int x1, foo, z1 // Create two sets of 'dump' values to dump the raw data into,
  int x2, bar, z2 // for the sake of a little smoothing.

                                 // the first box, it's ID is 0.
