Rhythm illusion

This renders the Risset rhythm illusion, the rhythmic cousin of the Shepard tone, where layered tempo cycles create a beat that seems to keep accelerating or decelerating without ever arriving. Hear it live in the browser, or render it from the Node CLI for a talk, a test signal, or further processing.
