Gal Sasson has put together an amazing puppet theater by combining art, music, theater, electronics, and computer programming. My mind is boggled by how far we have come from cardboard shoeboxes and sock puppets. I am guessing that Gal spent many hours designing, problem solving, iterating, and tinkering. Her passion and persistence have resulted in a truly spectacular product. Is there a way to measure her learning? Does it matter?
