Here is an interesting stereoscopic 3D POV video of a roller-coaster ride at the Linnanmäki theme park in Helsinki, Finland shot using two VIO POV HD Action Cameras
mounted on the head. The audio was recorded with a separate set of binaural mikes and a Zoom recorder in order to create a more realistic experience (watch the video with headphones for best results) almost as if you are in the first seat of an actual roller-coaster ride. And aside from the video having a bit more separation at the bottom of the frame the 3D effect is really nice, so do take a 'ride'.
