I talk about the power of pencil and paper when I speak at schools and libraries.
Tools that every kid knows how to use and yet, when combined with an active imagination, they are the best starting points for any type of idea: A film, a book, a video game. The humble pencil and paper is far more dynamic tool than my Wacom tablet or Photoshop or my iPad.
I have been working digitally for close to 16 years now but my sketchbooks carry my history is such a satisfying way. The biggest technology change to my pencil and sketchbook in that time is that I use automatic pencils now instead of having 4 or 5 sharpened pencils (well, they started out as sharpened) in my backpack. But keeping enough pencil leads in the pencil is easier than keeping a battery charged.
