from Click Z: "As part of its Red Bull Surfing team sponsorship, the energy drink company sent its creative agency Taow to film surfing action off the shore of Tahiti using a specially rigged 360 degree video camera from Immersive Media. Team members wore the camera in a backpack that filmed the area around them while they surfed last November... The resulting videos, now available on Redbullsurfing.com, use Flash to allow viewers to click and drag the perspective of the camera in whatever direction they choose."
There's more at Immersive Media.
Plus 360movies has QT videos, including an interactive video pano of a car race, and VideoThing posted More DIY 360° tests a few years ago.
