Nice.
Is the point on the left the start and end point?

Unfortunatelly not. Central point is used as first, fourth and eighth (last)
control point. The point on the left is sixth and I do not understand the sharp
shape there. I'm sure I used correct code since at first run I copy&pasted code
from GSL library without any modifications. See thread in povray.general
