Using a specially designed transparent 'canvas' to provide an unobstructed view| Picasso creates as the camera rolls. He begins with simple works that take shape
after only a single brush stroke. He then progresses to more complex paintings| in which he repeatedly adds and removes elements| transforming the entire scene at
will| until at last the work is complete.
