Wow. What had already been a Christmas season marked by flash mob videos -- these are videos of large groups of people appearing in a public space to perform a stunt -- took a whole new turn over the weekend.

By far, the most popular video of the season has been the performance of "Hallelujah" from a Canadian shopping mall, which, at this time, has been viewed over 23 million times. That came right after the Opera Company of Philadelphia received a lot of attention for their "Hallelujah" in a Macy's, which was a part of the Knight Foundation's Random Acts of Culture.

In the past few days, choirs from across the country have created their own versions, flooding YouTube with videos of their performances in bustling shopping centers. Here's just a few from the weekend:

Washington Square Mall in Tigard, Oregon	Upstate New York's Eastview Mall
West Side Market in Cleveland	Orlando International Airport
Westfield Valencia Town Center	Valley Mall in Hagerstown, Maryland

Add these to performances at the Devonshire mall in Ontario, the Hamilton Place Mall in Chattanooga, the Santa Rosa Plaza Mall, the Edmonton City Centre Mall, the Buckland Hills Mall in Connecticut Quail Springs in Oklahoma City, Lindale Mall in Cedar Rapids, Iowa, and Kildonan Place in Winnipeg, Manitoba. Then there're performances in Nordstrom's department stores in Seattle, Arcadia, and Dallas. And one in an atrium in Juneau, Alaska.

Plus, the one from Kansas City we mentioned this morning.

And there's more on this flashmob front...

On 1 p.m. Sunday, a huge group of people gathered (reportedly organized over Facebook) in Schaumburg, Illinois' WoodField Mall to simultaneously freeze in place to the surprise of Christmas shoppers. Here are two angles caught by some bystanders:


We've also been seeing groups of college students creating finals week flash mobs to break up their studying, with videos posted from University of Arizona, Illinois State, and now Oklahoma University.
