When I used *step = 0.095*, I have 64 frames, close enough to the wikipedia image's of 66.
But resultant animation is "choppy," where wikipedia's is fairly smooth. I tinkered with a spline to smooth out a different curve, but it ran fantastically slow, -- something about too many points? -- so gave up on it for this image. Thanks anyway. Will occasionally return to this -- the problem interests me.
