the point of this is,
that using zero-thickness tetragona (skwares) leaves a bit
to be desired, especially since this exercise shows some
of the grou[theoretical nature of "qyoobing".

to be more precise, show the a)
maximal hexahedral space, inside (the kernel), and b)
the minimal space around it (the hull, and c)
the symmetry, and obvious singularities
