But in many ; cases there is no loss, for there never was a goal in mind. ; ; The iterated expression, z=z*c^fn1(z), is simple enough, and the ; fractals it creates are mostly unimpressive, but once in a ; while, with the aid of an intelligent human, a notable image ; appears. Today's image, which shows the entire fractal rotated ; -90 degrees, is one of those rare cases. ; ; The image consists of a blue rainbow arching over a cold land- ; scape on an alien planet somewhere on the other side of the ; galaxy. I named it "Brainbow" in recognition of the part a ; human played in its creation. It is different enough to earn a ; non-inflated rating of 7. ; ; The render time of the included parameter file is 7-1/2 minutes ; on my cranky old machine. This time will be cut to a minute or ; two on the newest units that can actually run the file. In any ; case, the finished GIF image may be downloaded from the FOTD web ; site at: ; ; ; ; With total sun and a high temperature of 79F 26C, the Sunday ; weather was totally perfect here at Fractal Central, keeping the ; cats perfect also. My day was uneventful. Today is starting as ; near perfect as a day could be, leading me to expect another ; perfect day in all respects. The next FOTD will appear in 24 ; hours, but take note -- absolute fractal perfection is unlikely. ; Until then, take care, and don't get over-iterated. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= Brainbow { ; time=0:07:26.60--SF5 on a P200 reset=2004 type=formula formulafile=jim.frm formulaname=TestZero function=cotanh passes=1 center-mag=-7.88766/0/0.07092536/1/-90/0 params=2/0/3600/0 float=y maxiter=750 inside=atan periodicity=10 colors=0000AM0AM0BN0BN0CO1CO1DP1DP1EQ1ER1FR1FS1GS1\ GT1GU1HU1HV1IW1IW1JX1IY1KY1JZ1KZ1J_1K`1J`1Ka1Jb1Kb\ 1Jc1Kc1Kd1Me1Le1Of2Mg2Qg2Nh2Qh2Oi2Qj2Pj2Qk2Pl2Ql2P\ m2Pn2Pn2Po2Po2Pp2Pq2Pq2Pr2Ps2Ps2Ot2Ot2Ou2Ov2Ov2Ov2\ Ox2Ov2Oy3Nw3Nz3Nx3Nz3Nx3Nz3Nx3Nz3Ny3Nz3Nz3Nz3Mx3Mz\ 3My3Mz3My3Mz3Mz3Mz4My4My4My4My4Ly4Ly4Ly4Ly4Ly4Ly4L\ y4Ly4Ly4Ly4Ly4Ly4Ky4Ky4Ky5Kx5Kx5Kx5Kx5Kx5Kx5Kx5Kx5\ Kx5Jx5Jx5Jx5Jx5Jx5Jx5Jx5Jx5Jx5Jx6Jw6Jw6Iw6Iw6Iw6Iw\ 6Iw6Iw6Iw6Iw6Iw6Iw6Iw6Iw6Hw6Hw6Hw6Hw6Hw7Hv7Hv7Hv7H\ v7Hv7Hv7Hv7Gv7Gv7Gv7Gv7Gv7Gv7Gv7Gv7Gv7Gv7Gv7Gv8Fv8\ Fv8Fv8Gv8Gv8Hv8Hv9Iv9Iv9Jv9Jv9Kv9KvALvAMvAMuANuANu\ AOuBOuBPuBPuBQuBQuBRuCRuCRvCSvCSvCTvCTvCUvDUvDVvDV\ vDWvDWvDXvEXvEYvEYvEYvEZvEZvF_vF_vF`vF`vFavFavGbvG\ bvGbxGcuGcvGdvHdvHevHewHfwHfwHgwIgwJhwKhwLiwMjuNjw\ OkwPlwQmwRmwSnwTowUpwVqwWrwXswYtwZuw_vw`wwawwbwwcw\ wcwwcwwcwxcwwcwwcwwcwvcwv } frm:TestZero { ; Jim Muth z=p1, c=pixel: z=z*c^fn1(z), |z|
