You could probably use the blob pattern patch with eval_pattern() or 
eval_pigment() to do the same thing...it would probably render faster.
BTW, I have been working on adding new component types to the blob 
pattern. So far I have added "box"(pretty obvious), "pigment"(where the 
grayscale value of the pigment at each point is the field value of the 
component at that point.), and "blob"(which takes an ordinary blob 
object as input) component types.
