Kinderlab Robotics' Kibo Robot (http://kinderlabrobotics.com/kibo/) also features a tangible, screen-free programming language where the instructions are wooden blocks that kids put together in a sequence. They are a funded startup shipping mostly to schools and museums, and the whole thing is backed up by a long line of research first at the MIT Media Lab, and now at Tufts. Previously, the founders created ScratchJr. Worth checking out.
