The challenge about this challenge is really what I perceive to be a clash between the title and the description. To me, at least, the phrase "music of the spheres" evokes all kinds of mental images, but most certainly not literal spheres. As a matter of fact, I have two images that are titled "music of the spheres" and, creatively, "music of the spheres 2"; but neither of them has any spheres in them -- they have waves and curves. Softly undulating sheets of light and color. Am I alone in perceiving a clash here? So the trick, at least for me, is trying to come up with something that contains spheres but still evokes the idea of "music of the spheres" in me. Not a simple task, that. Good thing I have two weeks still left to try my hand at this...
