Edmund Scientific offers a camera integrated with goggles. They call it Liquid Image Ski Goggles and say it films from your point of view as you ski a mountain. It has 2 anti-fog treatment Lexan goggle lenses, Liquid Image Summit Series HD 720p Snow Goggle, Integrated True POV HD Video Camera, 136 degree (FOV) wide angle lens, HD 720p video mode Records at a rate up to 30 fps with audio, 5.0 MP still camera mode, Rechargeable 1200mAh lithium battery included for up to 1.5 hours of video. I see they also have liquid image goggles for divers. I don't know these products. Can they also be used when racing a go-kart or BMX bike?
