"Happy Halloween from the Google Doodle, which uses mammoth pumpkins and some pretty sophisticated pumpkin carving to send its holiday message. It's no trick and all treat. The Google Doodle often uses a static image when it temporarily revamps its home page. But Monday, users are treated to a time-lapse video showing huge pumpkins being sliced and diced and, as the sun goes down, emitting a flickering, ghostly glow -- and the name of the search engine, of course."
