I enjoyed reading this article. A graphic designer had to
  describe some of what he did for a living to a group of 4+5 year
  olds.
  *
  His answers and the way he went about it was brilliant.
  *
  So how do you describe "design"?
  *
  "Design is about making something easy to use, or easy to
  understand."
  *
  But what about "graphic design"?
  *
  "I use colours, letters and pictures to help people understand
  things."
  *
  The definition he gave for "design" was brilliant and
  surprisingly powerful. I wouldn't have thought of "design" in
  that way and yet, that's what it is isn't it?
