Looxcie wearable camera

“The Looxcie is not a high-definition camera. It records at a resolution of 480 x 320 pixels at 15″ frames a second. But it has a special button that makes it ideal for taking video of unexpected moments. When the camera is running in continuous-capture mode, and the wearer suddenly sees a goal scored at a hockey game, for instance, a quick push of the button will tell the camera to automatically save a clip of the preceding 30 seconds. The camera weighs about an ounce and stores up to five hours of video.”
