My theoretical go at it would be to describe a regular circle (local sin x , cos y) around the
z direction ( of a matrix at spline position).
Iterating the position of that matrix along the spline while
calculating the circle would then describe a helix along the spline.
(The movement along the spline corresponding to the "t" in that Helix formula)
