This name does not allude to ; a reggae song; it refers to the fact that at one point there are ; 12 elements surrounding the central midget, which is quadratic ; in nature and therefore not expected to have rings that consist ; of a number of elements that is a non-integral power of 2. ; ; The image might also be considered bad because it is unstable. ; The slightest change in the real(p2) parameter causes the entire ; scene to vanish. Finally, the two satellites in the northeast ; and southwest corners have six elements surrounding them, which ; is another wrong number. This image certainly earns its bad ; reputation. I don't know what it's going to do when they come ; for it. ; ; The generating formula is unusually simple. It takes Z^3 and ; adds somewhat more than half as much Z^5 before adding C. The ; resulting parent fractal is rather routine, except when the ; value of the parameters is near today's, at which point the area ; of the fractal where today's image lies becomes unstable. Like ; everything else in the world of fractals, this localized ; instability happens because of the things numbers do. Given the ; nature of complex numbers, it could not be otherwise. ; ; I rated the image at a 6, a rating that might be considered ; generous. The coloring is only moderately impressive, and the ; math interest is worth only slightly more. But then, a 6 is ; only slightly above average, so the rating will remain. ; ; The attached parameter file renders in under 6 minutes on my ; tired old P200 machine, which might soon be replaced as my ; fractal-dedicated unit. Those who would rather not wait 6 ; minutes to see the image may download it, already completed, ; from Paul's web site at: ; ; ; ; or from Scott's site at: ; ; ; ; I continue to find interesting things in variations I am ; creating of the recently posted Tman formula. Regardless of the ; number of dimensions, the images are out of this world. In ; fact, they're in the fractal world. Some unusual images could ; be coming in the near-future FOTD's. ; ; The Fractal Central weather turned milder, but remained too cold ; on Sunday for the dynamic cats to venture outdoors. There was ; some sun, but also flurries of snow, and a temperature that ; never reached freezing. The dynamic ones were surprisingly ; pleasant in the midst of their confinement. ; ; Today is starting milder yet. Could this be the day when the ; cats' paws reach the turf of the yard? Check in 24 hours to ; see. Until then, take care, and go where the fractals take you. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE================================ Bad-Boy { ; time=0:05:40.20--SF5 on a P200 reset=2002 type=formula formulafile=allinone.frm formulaname=MandelbrotMix4 function=ident passes=1 center-mag=+1.09529517003905100/+0.003871516957443\ 89/856841.9/1/155/2.75135829397310516e-009 params=1/3/-0.599/5/0/0 float=y maxiter=1200 inside=0 logmap=112 periodicity=10 colors=0004EO4FS3GX3H`2Ie2Ji2Jm6HmAGmEFmHEmLDmPBmT\ AmW9m_8mc7mg5mj4mn3mr2mv1my0mw6cvCUpCPkCLfCHaCCXC8\ SC4NC0ME2MF4MG5MH7MI9LJALKCLLELMFLNHLOIJPKIQLHQNGR\ OFSQESRDTSCUUEXVG_XIbYKeZMhYOk`QldUmhYmkcmnhmpnmrs\ mtrhprclrZhrUdrP`qKXqFTqAPq5Lq0HsAEtKCuU9vc7reDofI\ kgNhhTdjYakbYlhVmmSnrRonRokQohQodPoaPoZXbbcRfjEjq2\ np7npCnoHnoLnoQnnVnn_nncnmhnmmnmqninhfkcbiZ_fUWcPT\ aKPZFMWAJU5PT9UTCZTFdSJiSMnSPsSSi3uj5qj7mk9ikBfkCb\ lEZlGVmISmKOmLKnNGnPDoR9oT5oU2nW6nX9nYCmZFm_Im`Lma\ OibPfbPbbQ_bQWcRTcRPcSMcSIdTFdTBdU8dU7bV7`W7ZW7XX6\ VY6TY6RZ6P_6N_6N_7O_7O_7O`7O`7O`7O`7OaKOaLOaMOaNOa\ OObPObQObRObSOcTOcUOcVOcWOdXPdYQfZPd_Pd`PdaPebPecP\ ecPecPfcPfcPfcPfcPfcPgcPgcPgdPgePhfPhgPhhQhiQhjQik\ QilQimQioRjqSjsTjuUjwVjyWkzXkzYkzZkz_lz`lzalzblzcm\ zcnzcozcpzcqzcrzcszctzcuzcvzcxzcyzczzczzczzczzczzc\ zzczzczzczzczzczzczzczzcz } frm:MandelbrotMix4 {; Jim Muth a=real(p1), b=imag(p1), d=real(p2), f=imag(p2), g=1/f, h=1/d, j=1/(f-b), z=(-a*b*g*h)^j, k=real(p3)+1, l=imag(p3)+100, c=fn1(pixel): z=k*((a*(z^b))+(d*(z^f)))+c, |z| < l } ; END PARAMETER FILE================================== ; ;
