Hi!
Can be self shading. In the making of the sweep the individual spheres cast
shadows on each other. That's at least what I understood.
Adjusting the tolerance value in the sweep does not help here.

Just as Mike said:
         b_spline instead of linear_spline.
That's everything to change.
At least in povray3.6 on winXP.

Funny, that Y.Tanabe doesn't have these artefacts with MegaPov.


Yours,
Bu.
