I shot this with a Kodak PlaySport. Here's a brief review of the most current version:
The Kodak PlaySport (Zx5) is one of the best choices for a pocket HD video camera that anyone can use to make great HD video. It's waterproof, dustproof and dropproof. Perfect for dropping in a bag and taking on vacation. It has a glare resistant screen which actually allows you to see the screen in bright sunlight, online some other pocket HD video cams. Works great with iMovie and Final Cut X.
