This started out with a beach scene but when the foam layer behaved unexpectedly and gave me a circular hole in the middle it was begging for a vortex shader and that triggered a negatively displaced cone(circle SS shader...here's where my bad pun nature took over. I rendered it originally with an inapproriately fat chain for 8 hours to finish then remembered I had my modeling app back and made the chain in seconds.....re rendered a clip and composited it...
