Given enough pebbles and a large enough beach, you could make a drawing--and so a design--of just about anything. But this is arguably both a design and a concrete implementation of a kind of machine.

Your phone is just a drawing/design until you put energy into it as well. Then things start to "compute" due to the pattern of interactions that energy creates. There is no law of the universe that says this energy must be electrical.
