    Thanks. I just now managed to cut it down by quite a bit, but I think it looks too 'fat':

    #!/usr/bin/perl use strict; use warnings; ;$" =q%ef%;$_=q~my( $i,$x,$y,$p)=(0 ,0, 0,p op| |5) ;my $r= 2<< $p;my@i=m ap[(1)x$r ,2],1..$r ;subi{$i[ $x] [$y ]--}i;sub p{((1<$_[ 0]?$y:$x) -=1-($_[0 ]&1 )*2 ,i) for -1, 1}s ubf {my($p,$f)=@_;$ p--;my@m=($f,3- $f, 1-$ f); my@o=(3-$ f,$f,$f,$f-2)if$p>0;( $_&=3)for @o, @m; @o& &f( $p,pop@o) ,@m&&p(po p@m)while (@o||@m)} f$p ,($ p&1 )*2 ;su bb{y,y491 02, b#\ n,;print} map {bf or@ $_} @i~ ;y~ \n ~~d ;$; .=1;s&b&b &g;eval;# %$_+28;($ x-={}for@
      I think that is too obscure
