Risset Rhythm Generator
This illusion makes an audio loop sound as if it is speeding up (or slowing down) forever. Use the record function to capture playback to a WAV file you can use in your music.
The effect is accomplished by pitch-bending or time-stretching multiple layers of a loop played back at half/double/quadruple time. As the extreme layer fades out, a new layer fades in to replace it. It's like a Shepard Tone, but for sampled audio.
For the gruesome details, see Dan Stowell's paper on composing with eternal accelerando rhythms, which expands on Jean-Claude Risset's "Auditory paradox based on fractal waveform" paper (1986).

Each circle represents a copy of the loop. The numbers indicates the playback speed for each copy.
