Here's one that is sensitive to its environment. For the best effect, copy and paste the contents to perl's STDIN the first time you run this. Make sure when pasting the contents to a file that the last character is '_' and that whitespace has been preserved.

Yes, that might be a poor job of rendering a droid in ASCII art below the Death Star, but it does run for me. YMMV on that part.

               use warnings;
           use strict; my$foo;
         sub z{local$/;    undef
        $/;seek(DATA,       0,0)||
        return 0;$foo=      <DATA>;
        my @foo = reverse split//,
        $foo;return @foo }my$bar;
          for((z".rekcah lreP r",
          "ehtona tsuJ")[325..
              335,350..363])

             {$bar
          .=$_ if$_};
          print$bar||
          print "R2D"
          ,"2 says t"
        ,"his must be "
        ,"in a file in"
