Hi all, Apologies for posting something so similar to my previous effort, but the code is completely different in this one -

• it doesn't use VT100 codes (except \ec which i think works everywhere),
• everything is generated (except the shading scale) - compared with it being encoded in this
  theoretically you could make a new shape (along the lines of $x**2+$y**2+$z**2<$r**2 - which is used here)and it would work with that...
• it actually uses closest path shading to the lightsource

It's also 1 ball of code shorter (a standard i intend to start using - 1 ball =~ 200 chars :-D ).
anyway, without further ado:

          $_=q`$_='     
       @8GCI';@a=/./g;        
      $j=9;$k=9;$w=25;$            c=35;$e=   
     8;$u=2;$v=1;{$k+=$v*      =$k<6|$k>16?-1:   
    1;$j+=$u*=$j<9|$j>60?-    1:1;my(%l,$m,$n);      
    for$y(0..22){for(0..70   ){$r=($_-$j)/1.6;$s=  
    $y-$k;$d=(($_-$c)**2+(  $y-$f)**2+(($w-$r**2-$ 
    s**2)**.5-$e)**2)**.5;  if($r**2+$s**2<$w){$m=
     $d<$m||!$m?$d:$m;$n=   $d>$n?$d:$m;$l{$y}{$_} 
      =$d;}}}print"\ec";    for$y(0..22){print$_>6    
        9?$/:(($d=$l{$y      }{$_})?$a[($d-$m)*5/  
           $n]:$")fo          r(0..70)}select$q,  
                               $q,$q,.1;redo}`; 
                                 s#\s##g;eval
