Notes on a triangle

5 minutes

A brilliant ‘geometric ballet’ of sound, shape and symmetry on the theme of 180°

Over the last decade or so, the inherent beauty and elegance of maths has proven fertile territory for video artists looking to put their keen eyes, exacting minds and technical wizardry on display. But as the old proverb goes and this 1966 short film shows, there is nothing new under the sun. A classic production from the National Film Board of Canada, this short animated film sets some 300 transformations, divisions and subdivisions of triangles to a piano waltz, making for a viewing experience that still enchants 50 years later.

Director: René Jodoin
