The only change is a sign change in ; the iterated-expression line. As today's image shows however, a ; simple sign change can make a world of difference. ; ; The parent fractal is a Mandelbrot set rotated 180 degrees, so ; that its main spike points east and its East Valley has become a ; West Valley. If this were all there is to it, there would be ; nothing unusual, but a closer examination reveals subtle ; changes, especially in the West Valley area, where the sharp ; terminating point has broadened into a wedge. Today's scene is ; located on the southern edge of this wedge. (Strange things are ; also happening along the negative, in this case the positive, ; spike, but that's a story for another day.) ; ; With its herringbone patterns, the image is unusual enough to ; rate an 8, and the coloring is just strong enough to merit an ; extra half-point. Adding these together, the rating is an 8-1/2. ; ; The name "What is This Thing" is an easily answered question. ; This thing is a fractal, though I leave it to the more philosoph- ; ically minded to decide what a fractal is. ; ; The calculation wait of 4-4/5 minutes will pass quickly enough ; once the image starts to appear. The trip to the FTOD web site ; will be even faster. The web site may be found at: ; ; ; ; Heavy clouds, brisk winds, and a temperature of 36F +2C made the ; outdoors less than comfortable on Tuesday. The fractal cats ; spent the day ignoring the outdoors and keeping warm by the ; heat. My day was uneventful. The next FOTD fractal image will ; be posted in 24 hours. Until then, take care, do the things ; that are necessary and ignore the rest. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= What_is_This_Thing { ; time=0:04:49.57-SF5 on P4-2000 reset=2004 type=formula formulafile=basicer.frm formulaname=AllNewDivideBrot2 function=recip passes=1 center-mag=-0.2532112922284393/-0.0014744\ 9096068753/2e+009/1/-127.5/0 params=2.5/300 float=y maxiter=4200 inside=0 logmap=275 periodicity=6 colors=000jsBkoClkDmgDndEo`FpXFqTGqQGGdE8P70A16G4B\ L7GQALWDQ`GVeJ_kMdpPiuSWcLINE468859C59G59K59O5AS5A\ W5A_4Ac4Ag4Bk4Bo4Bs4Bw4Bt9EqDGnHIkLKhQNeWPb`R_dTXh\ WUmZRpaOsdLvgMwiMwjMwjNwiNwhNxgRxfUxeZxdcxdhydmydr\ ydvydzzdzzdvwarr_mnXhjVcfTZcQ__O`XMZUNYSNWQNVONTMN\ SKNPHNNDNK9NJ6NJ5NMCLOIJQOHRUGTZEUcCWhBXm9Zr7_w6Vt\ 6Qq7Kn7Fk8Ah8EiAIjBLkCPkDTlEWmF_mGbnHfoIjoJmpKqqLt\ qMooOjmQelS`jUWhWRgXMeZHc`Cbb7`d3_e7ZdBZcEZbIZaKZ`\ MZ`PZ_TYZWYY_YXcYWfYVjYUclwejsfhpggmheiicfjbck`_lZ\ XPjBShEVgGYeI`dKbbMeaOh_QkZSzDvwIptMjrQdoUZAmsFkoK\ ilPgiUefZcbca_h_X2w1Ep9QjGacN46uKGkZPbgMkhOhiPfjRd\ jSbkU_lVYmXWW8wYBtZDr`FoaHmcJjdLhfOzgQziSzjUzlWzgS\ zhTziUziUzjVzkWzkWzlXzmYzf7zZ9zW9zU9zT9zT9zT9zS9zS\ 9zS9zIUz9mzFmzKmzPmzVmz_mzdmziKzdKz_KzVKzQFzL7zR8z\ W8z`8zf8zk8zp8zu8ztDzsHzsLzrznqznqznpznoznoznmzjkz\ fizcgz_ezXzzzpzhrzftzduzb } frm:AllNewDivideBrot2 { ; Jim Muth z=(0,0), c=pixel, a=-(real(p1)-2), b=imag(p1)+0.00000000000000000001: z=(-b)*(z*z*fn1(z^(a)+b))+c |z| < 1000000 } ; END PARAMETER FILE========================================= ; ; ; ; _______________________________________________ ; Fractint mailing list ; Fractint@mailman.xmission.com ; http://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint
