Yes, it's mud. Shot this with the Lumix point n' shoot. Desaturated the yellows somewhat, and did a curve adjustment in Red to get it here. One might be tempted to wax philosophical and suggest that this is, in fact, a letter. And as such, will sit here communicating whatever it communicates, symbolizing whatever it symbolizes, from now until whenever, where "now" is your now, my now, all our nows... wherever this picture and its referent happen to appear.
