Try this as a starting point. You should be able to introduce some randomization and rounded corners.

  def a_tiless (expr p) =
  T:=identity;
  pickup PenC;
  path q, qq; q = bbox p;
  picture tmp_pic; 
  uu := max(u, (xpart urcorner q - xpart llcorner q)/100, (ypart urcorner q - ypart llcorner q)/100);
  tmp_pic := image(
    for i = xpart llcorner q step 2uu until xpart urcorner q:
      for j = ypart llcorner q step 2uu until ypart urcorner q:
        qq := punked (((-.5uu,-.5uu)--(.5uu,-.5uu)--(.5uu,.5uu)--(-.5uu,.5uu)--cycle) 
	   )
            shifted ((.6i,.6j) );
	if xpart (p intersectiontimes qq) < 0:
	  thclean qq;
	  thdraw qq;
	fi;
      endfor;  
    endfor;
  );
  clip tmp_pic to p;
  drawoptions();
  draw tmp_pic;
enddef;
