What shall I choose? Headbangers' theme Simply Light? Not only do I have to choose something that will well illustrate the theme, but it will also have to fit into the elongated rectangle which I insist on using for my header. The lights at Safeco Field--"The Safe"--when we went to a Mariners game last summer might do.
Or how about a different meaning of light? This feather is light.
And what lighter than the ubiquitous dandelion fluff.
But no, I have something even better to represent this theme. It is a classic interpretation and I think you will like it.
