Hi!

Is it possible to color a sphere_sweep along the spline? I.e. with a
gradient that follows the spline instead of fixed direction. As the
spline twists in all directions I can't fake it by using a standard
gradient. I tried to transform the spline coordinates to something more
accessible, but that fails because one has no possibility to know how
far on the spline a given point (x,y,z) is. But perhaps I'm missing
something :)
