To expand on this, Famous's Node class [0] is rather like a DOM node, except far more powerful. You could imagine a React component that renders a tree of virtual Nodes, diffs that with an existing tree, and transitions properties accordingly. But that will be built on Famous, just like react-canvas [1] needed the canvas API to exist. Baby steps.
