If you watch the video on Vimeo, there is a link to how they did it and some of the planning stuff and how they modeled from some of the images. Amazing work, thanks for posting it.Alan
All I'm seeing is the "Behance.net" link under the Shorpy.com link that only shows individual frames of the video so could you provide the link to the video that shows how they did it? I'm not finding it.
