Thomas the (demented) tank engine

My friend Justin's son Emmett, 3 1/2 is brilliant, curious, audacious, mischievous, verbally advanced, strong willed, and divides the world into things that roll and things that don't roll. When he exclaims "it rolls," it's like a stamp of approval. So I made this for him. It's large -- 6"X8"X4" -- and I'm making a smaller version for Kas, my grandson (2 next month). Also building a busy board and my big Spring project will be an adjustable easel that accomodates a big roll of paper.
