Differential dynamics is a kind of motion - periodic motion - that was originally described by John Whitney Sr. in his book Digital Harmony. One can’t really say he discovered the phenomenon, but he did discover a proper application for it in visual music. Whitney believed the cyclical tension and resolution of differential motion was a fitting match to musical structure.

Here is a demo of differential dynamics I mocked up using a sample program he outlines in his book.
