looks very good! :-))

Can you make the radius of the knotholes more randomized? it looks strange....

Thanks.

Not that easy, they are repeated black_hole warps, and the turbulence only
affects position.  I will probably have to use more different warps, right
now there are only two of them.

Couldn't you do it using vturbulence() or vwarp()?

Or you could just generate a bunch of randomly placed ones, possibly 
using a pigment to control their distribution(with eval_pigment()).

Neat! :-)
What pigment did you use for the displacement? And what kind of 
displacement?

These are very nice results...keep up the good work.

That's an interesting idea, don't know if it will work, but i could try...

type 1 displace warp with spotted pigment, it's not very elaborated so
there's probably room for improvement.
