One might assume that Google's 2011 Halloween Doodle, an elaborate time-lapse video of the Google Doodle team and friends carving a bunch of gigantic pumpkins in the form of the company's logo (Google also released a making-of-the-doodle video), would be tough to beat, but the leader in the early voting is underdog Microsoft Bing's picture of the day — a dark and striking time-lapse composed of photographs showing a lightning storm flashing across a menacing gargoyle. So, which company better captured the spirit of Halloween? Any other sites deserve special mention?
