This fractal makes a web in a very different way than the Web Rings fractal I posted previously. By pure chance, this fractal has an area with two closely spaced spirals that rotate in opposite directions. The opposite rotation seems to cause arms to connect the two spirals. I zoomed in using mostly trial and error to find this fractal. The last zoom was particularly surprising as it changed the rings into a mesh. The equation is: z = 1 / (1 / ((z ^ 3) * tan(z) + pixel + 1) + 1 / (z ^ 4 + pixel - 1)) Here is a link to an image: http://dl.dropbox.com/u/33642054/image/web_opposition_1200_5.jpg The Fractint compatible PAR file for the image is: Web_Opposition { ; Exported from Fracton. reset=2004 type=formula formulafile=fracton.frm formulaname=F_20121113_0951 passes=1 float=y center-mag=0.706758545849994/0.2398003577709398/15\ 686274705.88235/1/17/0 params=1/1/4/4/-1/0/1/0/0/0 maxiter=2000 inside=0 logmap=128 periodicity=6 colors=000JqzLqzNqzPrzRrzTszVszXszZtz`tzbuzduzfuzh\ vzjvzlwznwzpwzrxztxzvyzxyzzzzyzzxzzwzzuzztzzszzqzz\ pzzozzmzzlzzkzzizzhzzgzzgzzgzzgyyfyyfxyfxxexxewwew\ wevwdvvduvduucuuctucttbstbssbrsbrsarraqraqq`pq`pq`\ op_op_oo_no_noZmnZmnZlmYlmYlmYklXklXjkXjkXikWijWij\ WhiVhiVgiVghVfhUfgUfgUegTefTdfTdeSdeSceScdSbdRbcRa\ cRacQabQ`bQ`aP_aP_aPZ`PZ`OZ_OY_OY_NXZNXZNWYMWYMWYM\ VXMVXLUWLUWLTWKTVKTVKSUKSUJRUJRTJQTIQSIQSIPSHPRHOR\ HOQHNQGNQGNPGMPFMOFLOFLOELNEKNEKMEJMDJMDILDILCIKCH\ KCHKBGJBGJBFIBFIAFIAEHAEH9DG9DG9CG9CF8CF8BE8BE7AE7\ AD79D69C69C68C68B57B57A56A46A469459358348348337237\ 23622612611511500400401502603713814915A16A17B27C28\ D29E2AF3AG3BH3CH3DI3EJ4EK4FL4GM4HN5HN5IO5JP5KQ5LR6\ LS6MT6NU6OU7OV7PW7QX7RY7SZ8S_8T_8U`8Va9Vb9Wc9Xd9Ye\ 9ZfAZfA_gA`hAaiBajBbkBclBdlBemCenCfoCgpChqDhrDisDj\ sDktDluElvEmwEnxEoyFpzHpz } frm:F_20121113_0951 { ; Similar to the parallel resistance formula a=real(p1),b=real(p2)-1,d=imag(p1),f=imag(p2), z=0,c1=pixel-p3,c2=pixel-p4: z=1/(1/(a*(z^b)*tan(z)+c1)+1/(d*(z^f)+c2)), |z|<100 } -- Mike Frazier www.fracton.org
