Facebook recreated the roaring '20s for a blowout, Great Gatsby-themed holiday party

Facebook went for a blast from the past for its annual holiday party on Friday night, with a roaring '20s theme that featured flappers, acrobats, and lots of ornate jazz-age decor.

The Great Gatsby-like theme seems especially apt for the current boom time, in which a new class of internet entrepreneurs has amassed immense wealth and power. The party has moved from West Egg in Gatsby's day, to the West Coast - Silicon Valley in particular.

Of course, Facebook founder Mark Zuckerberg recently vowed to gradually give away 99% of his wealth to support various causes, providing a contrast to the unbridled excess and extravagance of the 1920s.

Facebook's employees have plenty to celebrate this year, including growing the social network's audience to 1 billion daily users. On Friday night, they gathered at the San Mateo Event Center to toast the good times in high fashion. Here are some of the highlights.
