From 1929, a splendid experimental animation that imagines life's origins

Tusalava (1929) is a splended experimental animation by New Zealand avant-garde filmmaker and kinetic artist Len Lye. The original film featured a piano score by Jack Ellitt that has unfortunately been lost. (The video above has contemporary music by Andrew Pask who uploaded the film to YouTube.) From the Len Lye Foundation:

The film imagines the beginnings of life on earth. Single-cell creatures evolve into more complex forms of life. Evolution leads to conflict, and two species fight for supremacy. The title is a Samoan word which suggests that things go full circle. In this film Lye based his style of animation partly on the ancient Aboriginal art of Australia. Tusalava is unique as a film example of what art critics describe as "modernist primitivism". In contrast to the Cubist painters (who were influenced by African art), Lye drew upon traditions of indigenous art from his own region of the world (New Zealand, Australia and Samoa).
