This clip was very hard to put together. There is a break in the film about midway. This is because the film went completely blurry and the frames could not be interpreted in any way. The film then continues until the film subject actually bends over forward. At that point the first walk sequence ends. It ends on a very blurry frame, so I back it up to the next clearest frame.

This clip will take you all the way to the last clear image on the first walk sequence. In that last image, the subject has fallen forward, with the buttocks showing toward the camera. The second sequence begins on another part of the sand bar, and need not be connected at all with the event seen here on this post. This file, at the last, oscillates back and forth so that the upright posture and the fallen posture can easily be understood. Click on the image to animate.
