After thinking about this for awhile, the fact that this is the trunk of a grape vine kept retuning to my mind. So here is my idea. I thought of a very ancient grape vine that was growing on an old wall or rocky outcrop and then i started to see the vine wrapping it self around the pot and cracking it with it's slow but tremendous strength. So how about a drum pot with a vine effect appearing as though it has grown around the pot and from this the appearance of cracks running out from the vine as though the pot is ready break under the pressure. The foot on the right would actually be the vine. The pot would be finished in earthy unglazed tones.
