something like this ?

light_source{y#local g=function{abs(sin(9*sqrt(x*x+y*y)))*pow(3-min(3,sqrt(x
*x+y*y)),2)/z+.9}2}sphere{20*z#macro p(Y,C,X)#if(C)g(abs(x)-X,y-Y,22)*p(Y-2C
-1X)#end#end 9pigment{function{p(4,4,4)p(2,2,0)p(4,1,2)1}}}//M

increasing/decreasing 22 you can simple control visibility of this relief
