Syncronizing Metronomes

64 Metronomes
1 Table  (able to swing on the same axis as the metronomes)

(gotta love that little rebel at around 2:40min  )

Why do I consider this a fractal?
Its a feedback loop, a recursive process.
Each metronome is giving and receiving feedback (kinetic energy) from all other metronomes, connected through the movable axis of the table.
Essentially it is this what happens:

self oscillations has to do with the solutions to the denominator of the transfer function, I was taught in college
