As an elementary art educator, I was impacted by the universal use of symbols my students incorporated into their art.  Particularly, happy symbols.  Happy houses with chimneys complete with curling smoke coming out the top.  Double storied (for lots of kids)  and windows with old-style cross-bar structure.  Ironically, when given a chance to design my own home, I built something very similar to those I have drawn from childhood.

People across the world have drawn simplified human form, such as that depicted.  Simple in form, but complex in meaning.
