VIDEO: As the GOP convention hall turns

Organizers of the Republican National Convention recently posted a time-lapse video of the first week's renovations at the Xcel Energy Center in St. Paul, Minn.

Their Democratic counterparts in Denver are similarly documenting the many changes at the Pepsi Center, but "the footage won't likely go public until much closer to the Convention - to preserve the element of surprise around our podium design," according to spokeswoman Natalie Wyeth.
