Wired 13.01: PLAY: "A 13th-century knife found in an extinct Norse colony
in Greenland has a full handle, but only a stub of metal blade,
sharpened away to nothing. At the quarry on Easter Island where the
giant stone heads were carved, the biggest ones lie half finished on
the ground, the work interrupted by social collapse. They are signs of
desperation, the product of folly."
