The trick behind this transformation is a stretching for the sides.
As you can see the matrix is not:
1 16 0 0 0 1 0 0 0 1 0 0 0 1
first of all it is changed in its dimensions like:
1 16 0 0 0 16 0 0 0 8 0 0 0 2
then the angle correction for z_y is added:
1 16 0 0 0 16 0 0 0 8 0 0 -16 2
in the last step it is moved into it's final position:
1 16 0 12 -28 16 0 0 0 8 0 0 -16 2
Just play around with the other 0 values and see what will happen.
