Sebastien Helie sent me an email with an interesting new fractal parameter file in it. He said:
I leave you free with the decision of what to put on [the Fractint email list serve] (if you put it on). the fractal is super cool. I ... wish to the group a merry christmas I agree with him about the fractal being pretty nifty, so, below are his parameter file and a link to an animated gif of his fractal on my server.
It's a "passes=o" (orbital) which I have not used before. Interestingly, different pixel resolutions (image horizontal and vertical sizes) give slightly different versions of his fractal. I used Richard's Fractint for Windows beta 5 (not for general release; now renamed Iterated Dynamics). Even 1280x960 size images continue to evolve over time in a pleasing way. To try to reproduce a little of that "flavor," I saved his image approximately every two seconds, and combined the ten versions into an animated gif of the evolving fractal. You *really* need to view the animation at full size. If the browser shrinks it, all the pixels' colors are muted, and the curved arrays of single pixels get blurred. It's a little over three MB: http://tinyurl.com/Owl-Orbit-animated-gif or: http://www.emarketingiseasy.com/Sebastien/Owl-Orbit.gif --------- Start of his parameter file: ------------------- owl_orbital { ; 3 2017-12-06 by Sebastien Helie reset=2004 type=formula formulafile=2012_7.frm formulaname=startail passes=o center-mag=1.34954/-0.000501549/0.6005002/1/90/3.88578058618804789e-016 params=0.707106/1/2.4142/2 float=y maxiter=2500 inside=0 cyclerange=1/1 colors=000<3>000000000000CCCOOOZZZhhhpppvvvyyyz0W06a0Cg0Hl0Mq0Qu0Tx0VzWW\ GaPMgJSlEXq9au5ex2hz0jz8k0F00K00N00P00N00K00F0888F0FK0KN0NP0PN0NK0KF0F00\ z<8>ZZnbblffk<3>vvezzz0vv<7>0SS0OO0KK<3>044UUo<2>eecii_kkXmmVooUooUooUmm\ VkkXii_<2>YYk0Uo<2>CecGi_KkXOmVSoUWoUZoUbmVfkXji_<2>vYk0zm4vh8rcCn_GjW<2\
