[math-fun] Fwd: Fourier synthesis of (cos(4 sin t), sin(4 sin t))
(overmodulated FM): gosper.org/Besser.gif The harmonics are Bessel coefficients. --rwg Someone complained of seeing only an inanimate blue rectangle. Let me know if you too see a stiff gif.
("Stiff" as in "rigor mortis", I presume.) I am happy to report having experienced vigorous animation; however, I fail to grasp the significance of the RWG colour scheme. [ I seem to remember scratching my headf over this question before, then resolving it to my satisfaction --- but am now unable to repeat the feat. ] WFL On 2/6/16, Bill Gosper <billgosper@gmail.com> wrote:

I believe the color encodes winding number. On Sat, Feb 6, 2016 at 9:39 PM, Fred Lunnon <fred.lunnon@gmail.com> wrote:

Exact;y. With a bunch more Bessel-weighted rotors (harmonics), you can make a *really* overmodulated one that winds several times around before reversing. --rwg Morwen Besselweight--the famous cubologist?
