There are a lot of these home-made pinwheels about, most of them made using recycled materials (Kitakyushuu city enjoys to boast that it is one of the cleanest cities in the world)
Interesting objects, those pinwheels, and interesting notes to go with them. They are good subjects for photography. You need to find some that don't have such a busy background. I like this shot, and I'd like to see more of the pinwheels.
