OMG, meow's 61 is out of this world: so simple and so hard to see, at the same time. :)
(half a star less, for author's over 50 steps off from what his creation offers :)) ).
Just like JeffB and yokosooo I had a 73, first. Then found a 69 and a 67 and am still stuck 2 off. Will keep trying. It's a hot-burger. ;) :))
EDIT (6 days later): Finally found the 65. Very nice find, FlashBack.
