The woman and man are clocks. In my opinion is that every person has his own time on this earth. The clocks behind their backs represents the time that they have. The woman and the baby represent the reborn of a new hope. If you saw the movie" The Truman Show" you will understand what the murals represent. Or Matrix. It represents the technologies that is all over around us and how addicted we are from it. And the beard man represents the caretaker( a god) who watch mankind and he take care so all the people respect their time on this life.
