One of the things I learned about photography is to try to avoid putting labels on things, especially when one is presenting an image to a first time viewer. That way, people can decide whether they like an image or not on its own terms. So I decided to avoid titling this image to see what people think about it.
Edit: So in order to avoid wasting space and time, I have added a few more images, which are obviously in colour. Isn't Spring wonderful.

PS Don't worry Fred, the last swirl image is just for fun!
