We saw this tree-thing outside in our neighborhood. With a quick look it doesn't look like a tree, only a few circles as they go on and off. But with a long shutter time you see all of it. That gave me the idea to experiment. I used a tripod, but the wind was really strong... Something to try again next year. The home owners came home and I feel a bit odd to go there again this year...
Used as a filler.
