Four years ago, Danny Boyle unveiled his opening ceremony for the London 2012 Olympic Games.
Isles of Wonder was based on the transformation of Britain, from a "green and pleasant land" to the internet era, via the industrial age.
A cast of 10,000 volunteers were involved in the memorable £27m show, which featured farmyard animals, several Voldemorts and even James Bond.
Its creation was captured by Ben Delfont, a stage manager for the event.
