The path of a thin strip of that is a helix, e.g. if you set the limits
to <pi,0> <8*pi,0.01> then you get a thin line that follows a helical
The problem is that the width of the ribbon consists of points that are
always in the positive x and y directions, which isn't like anything
This gives a ribbon that has a surface parallel to the axis. The
ribbon's width is in the z direction.
This gives a ribbon that has a surface that is perpendicular to the
axis. The ribbon's width is outwards from the centre in the direction
