Art of Nature: Fascinating Form of Vine

So I headed back to the mountainous village to search for some nature shots this afternoon. What fascinated me was a vine that looks like a vehicle spare part (per) and I thought that was a kind of nature art. I made a couple of shots from various angles to get a good result even I understood those are not as perfect as a pro. I often get confused when dealing with the name of my nature shots. Some are available on the internet, some are not. Like this unique form of nature, even I tried so many times to look up its name, I am still not able to find out. What I can offer you this time is some art of nature pictures that I recently took in the mountainous area, near my village. I really hope you like my amateur shots.
