Hmmm... a japh-like idea I had when I was looking at a page-layout engine design at work. I didn't have time to obfuscate it really hard, and will take suggestions.

There's just a bit of mild obfuscation, a couple of odd syntax tricks, a few little-used Perl features. This is a straightforward one to take apart, and it's 5.6 clean. Enjoy! 

#!/usr/bin/perl -w
$s=2;($p)=@m=(0,0,1,0);$/=\1;
sub t{@m[2,3]=(0,0);for$y(split//,$_[0]){for(2,3) {
$m[$_]+={n=>[-1,0],s=>[1,0],e=>[0,1],w=>[0,-1]}->{$y}->[$_-2];}}}
$SIG{__WARN__}=sub{$p=!$p};seek DATA,0,0;
for (qw(    6   se   p 2 e    2    ne 
            2 n    5 p     e  2     s 
            8 p    n 6     ne 2     e 
            1 se 2 s 5 n 2    w 4 e 4 
            p e    2 s        3     p 
            n 8    e 4        se    1 
      s     2 sw   1 w        4     p
       se   4 e    3 p        n     8 
         s 4  e    4 n        4     s 
          7 
)) { $_[0]=$_;tr/nsew//?&t:&f}
sub f{for(1..$_[0]*$s) {for(0,1){$m[$_]+=$m[$_+2]}if
($p){while(<DATA>){$t=$_;tr/\n\t //||last;}}$g[$m[0]][$m[1]]=$p?$t:" "
+;}}
for$i(0..20){for(0..60){print $g[$i][$_]||" ";}print"\n";}

PS: Change the $s=2 to another positive integer to change the scale. The 20 and 60 may also have to be changed if you go large. You will have to run this from a file.
