I don't know if anyone else will find these pinwheel pictures fascinating, but I do. I love the interplay of colors and lights and wavy shapes. And yes, these are those simple, cheap, children's pinwheels that you blow on to make them spin. But it's totally cool-looking when you zoom in up close.
I love the subtle differences in lighting, textures, focal points, angles, colors, etc. That's why I take so many pictures of the same flower. Oftentimes, I can't decide which one I like best, even though the differences are small. (And these don't even include all the ones I deleted.)
