This is just a special case of Distorted Columns, Lines, or Waves. The shape
of the setup is that of waves after and Ends Press Ahead or Centers Press Ahead.
Such a setup contains two Z's, but this concept removes the distortion, so that
the Z's don't explicitly exist. Hence it is illegal to call something like
"Z Lines Z Axle", since Z Axle requires an explicit Z. Shape-changers are not
allowed with this concept.
