Cold cog

The larger scale is a nice extension of your exploration of the cog. This is a  remarkably elegant work.

Thanks for your comment on the scale. I spent 4 hours on a frozen lake with an ax caving the cogs out of the ice. When I saw the video images, I though the cogs looked like they were 4 inches not 4 feet across.
