Oddly enough, the 3.0 source had some of the support code for a 
so-called "spiral" warp, but it was never implemented.  The code 
was removed in 3.1.

All of these ideas, with the possible exception of the falloff
stuff, are very easy to implement.  The crystalline lattice 
could be implemented as yet another patch to the crackle 
pattern - I would say a syntax something like 

crackle {
  centers {2, <0,0,0>, <.5,.5,.5>}
}

but with a better keyword than "centers", of course.  I had thought 
at one time of making crackle 2d as well, but with the planar warp in 
the new superpatch such a thing is redundant.
