Not here, but would be interesting to see the annimation.

What didn't work with fewer?

I'm not a great user of POV-Ray's splines, but you do sometimes have to 
overlap on loops to get continuity or completeness. Never heard of 
anyone needing 8 additional values of both ends though. More wouldn't 
hurt I guess, so long as you are still picking off the loop values you 
need from the middle of the spline.

I'm not an animation guy, but cool trick.

Glad you're back.
