Watch on SFlix. DEMOLITION OF A WALL takes six frames of the falling wall from the 1896 Lumiere film and reorders these six frames in all their permutations. With a score for piano that follows a similar pattern the film resembles change ringing, a musical form developed in England in the 17th century where the tuned bells of a church tower are rung in a series of mathematical patterns called "changes". Here, we see 718 additional variations on the original "theme".
