Using art to teach

It's funny how when you discover a passion you start to filter everything through that.  Mine currently is games and I'm trying to infuse all my teaching with that.  A student of mine is trying to do everything through art, so for example she taught a whole lesson on space to 2nd graders by having them do art.  She was ust here telling me about an "art enrichment" day she prepared for the primary students whereby she invited 16 different kinds of artists (dancers, singers, painters, fashion designers etc) to teach a workshop on the theme of bullying using their art form.
Whatever your passion, use it to teach.  What's yours?
