Awesome !
I must do something wrong when I am trying to reproduce the examples because in the Visualization section I am getting an error:
SplineKnots specification {Automatic, {0, 0, 0, 0, 0, 0, 0.5, 1, 1, 1, 1, 1, 1}} should be Automatic, "Clamped", "Unclamped", a non-decreasing sequence with proper length, or a pair of such values.
Everything before this section is working.
