Are you thinking of something for the gradient of a pattern? A pattern 
that would return higher values in areas that change rapidly, but 
approach 0 in "flat" areas? The displace warp can do something similar, 
the code could probably be modified to do this pattern(maybe a more 
general pattern that calculates the "amount of warping" for any warp). 
Actually, you could probably do it with an isosurface function...I don't 
know how useful it would be in isosurfaces, though.
