Google and Bing celebrate Halloween with a time-lapse video. Both are found on their respecitive home search page. Google's video features Googlers carving six giant pumpkins to spell out the search giant's name. Bing's video highlights a spooky scene when serves up on FireFox or Internet Explorer. Chloe Albanesius points to a post on the History Channel site that tells us U.S. growers produce 1.5 billion pounds of pumpkins each year, more than twice the weight of the Empire State Building. Happy Halloween.
