It's one of the painful paradoxes of the creative process that you have to be ready to throw away what's most important to you. You have to not care (about failure) to convey the confidence that lets you communicate in a convincing way.
I've also found that a lot of good things happen in the middle of doing something else, when intent and caution are not "in the way."
And that's what this picture is: something that happened while I was trying to do something else.
It's a cliché in other ways too: a figure on ground, a mystery material in a well lit space. It's so simple it's nearly nothing. That's probably why I like it.
