I don't know about other artists, but I am always trying new methods of creating.  When I first started, I worked with a number 2 pencil almost exclusively but I was always making things in other mediums.  I tried building things with toothpicks after I saw a show.  My favorite toy was Legos.  I would hide away in a corner and no one would hear a peep out of me.  Loved playdough and thought I would become a sculptor, even now I often think of working in clay.  

Whenever I see a form of art done well I want to try my hand at it.  Unfortunately, time and money make this hard to realize.  After all there are only so many hours in a day and my patience with the process is not as good as it should be.  I want to be great out of the gate.  Still, most of time I am happy to putter with new ways to express myself.  The best time I had in college was when I took a sculpting class.  For my final project, I made a plaster scupture of what looked like an egg pod from the movie Alien splitting open.  I made it to look like a human brain and the base was held up by roots.  On the floor under the piece I got some green felt and layed lines of numbers and letters feeding into the roots.  Out of the opening at the top of the pod I used thin dow rods that had butterflies at there end that had famous equations and quotes like E=mc^2.  What was I expressing there eh?
