Many SIRDS come with two dots below them to make it easier to see the Image -- you relax your eyes andlet the two dots blur into four dots, and when the middle two get closer together, you try to "focus them" so that they become one clear dot (at which point the image appove will magically reveal itself to you).

You can add this to the bottom of abstrats's code to generate those "dots" and make it a little easier to see the images... 

END {   print "\n",' 'x35,'X',' 'x15,'X',' 'x35,"\n";  }
