Self-replicating code? Not exactly.
print map{$i=$_/ 20;$/,map {$r=$; =$_/20;$ z=$i; $n=$z*$ z,$z =2*$r * $z+$ i,$r= ( $m= $ r*$r )-$n+ $ ;for a..z; $ m<4? $":"+"}- 46.. 13}-20..19 #GEB?

    This version shows a little more fine detail around the edges:
    print map{$i=$_/20 ;$/,map{ $r=$;=$_/ 20;$z= $i;$n= $z* $ z,$z =2* $ r*$z+ $i ,$r=($ m=$ r *$r)- $n+ $ ;for a..z;$ m<4?$" :chr(40+ length$m) }-46..13}-20..19#!
