When I was young – in junior secondary school, as I recall – teachers occasionally treated us to a National Film Board short (a treat for them more than us, perhaps). Among the best were the works of Norman McLaren, who achieved international recognition as a Canadian pioneer in animation and filmmaking.
Here’s a contemporary treatment – Choros – by Michael Langan, who “uses new digital innovations to layer some 32 sequential instances of a single movement and then stretch it out over time,” much as McLaren did.

Compare Choros to McLaren’s Pas de Deux here, with similar effects after 7:45.
