Marcus du Sautoy has teamed up with animator Simon Russell to create this animatino to accompany Messiaen’s Quartet for the end of time. It’s got all the usual arty maths things in it – the Fibonacci sequence and golden ratio, prime numbers, polygons and polyhedra of all sorts – as well as the less well-trodden sporadic group $M_{12}$. It all comes together quite nicely, though I much prefer the elegant end to the spiky-frenetic start.
