That is way cool!

I don't think I'm spoiling it by showing the end result, because the best part is watching it get there!

It gives:

                    (@e)}fo
     r($xp         ++){@camel=
  2@me},9.       .12);$xp=('0,
  'x7).('1,'   x16).('2,'x22).(
     '3,'x27).('4,'x27).('5,'x29
    ).('6,'x31).('7,'x31).('8,'x
    31).('9,'x30).('10,'x27).('11,'
    x26).('12,'x16).('13,'x9).('14,
     'x7).('15,'x7).('16,'x5).('17,
       'x6).('18,'x7).('19,'x10).('20
        ,'x3).'20';@xp=split(/,/ ,$
         xp );@e=(e),@e=_(@e),pc(@e)
            ,sele    ct$,,   $,,$,,
             3;for             (1..
             64)               {@e
             =_(               @e),
             pc(               @e
            ),I                ,se
            lec                t$,,
          $,,$,              ,.05;
         @e=c

I particularly like

for($xp++){@camel=@me}

I've ran out of votes today I'm afraid ;-)
