Apparently I have too much time on my hands... This isn't so much an obfu as I just wanted to see if I could do it w/ a regex and w/o leveraging the typical methods of reversing a string. And it didn't really seem to fit anywhere else :) 
$_='?od lliw xeger a nehw noitcnuf a esu yhW';
while((s/(.)$/$,.=$1;$==length$_;($=!=1)?'':$,;/e)&&($=>length$_)){}
print "$_\n";
