Yup - you nailed it smile emoticon That's what I was shooting
  for. I love that I have the capability in the palm of my hand,
  wherever I go, to almost thoughtlessly make a little art piece.
  With some care and attention, a few messages about the
  environment or something about human activity, it could get
  people to go, "oooh" and "ahhh" and such. For me, it actually
  does have a deep meaning - the systems involved in processing
  things like water are fascinating and meaningful to me. In a
  sense, this _does_ point to a deeper 'something' I believe in:
  not saving the environment really but rather appreciating how
  far we've come, how far we have to go, and being grateful where
  we're at right now. I wouldn't say this is my best _expression_
  of it: it was quick and not thought out. But I wanted to share,
  to test how a fast capture of an idea might be received in
  different environments, so that if I *did* spend some good time
  working on something I put my heart into, the kind of reception
  I might expect.
