Attached an image where I filled text object characters with noise as a 
function for an isosurface. Here not that fast because the inside test 
for a single text string like "Halloween" is slow.

#declare Fn01 = function {
     pattern {
         bool_object {  // In POV-Ray proper this called 'object'
             text {     // yuqk has also list_object etc.
                 ttf "timrom.ttf" "Halloween"
                 0.15, 0.001
                 translate <-2.0,0,0>
             }
         }
     }
}
#declare Fn02 = function (x,y,z) {
     (Fn01(x*3,y*3,z*3) > 0.0)*f_popnrm_rnoise(x,y,z,now,1)
}

No real shape - just enough +-noise that the isosurface root finder 
finds plenty of roots.
