The trunk and branches have a square-root-2 rectangle as cross section.
The cut faces are squares.
No two branches point in the same direction,
giving rise to its irregular (wild) appearance.
In this skew variant, the left and right branches are not placed symmetrically,
breaking the rotational symmetry.
Compare to Wild Fractal Tree,
which has a half-turn rotational symmetry about the vertical axis.
