Wild Brains
by Mike Frazier 11 Sep '15

11 Sep '15

This fractal mixes cos and z * sin. It has minibrots surrounded by arms made up of smaller triple arms. Each minibrot in the area is a bit different than the others. The structures surrounding the minibrot look a little like brains and the colors are wild so thats how I picked the name.

Fractint triumph.
by John Wilson 07 Sep '15

07 Sep '15

Been playing madly with my machines—got my Asus Chromebook to run DOS! How? Using a DosBox installation. Why? So I can run Fractint in there. The machine runs for 12 to 15 hours between charges—no hard drive to drain the battery. So I can play Fractals in the coffee shop or read a book! Offline. Fractint seems quite fast, and I have some adjustments yet to make. Now I'm ready for that slacker, Jim Muth, to fulfill his promises. ☺ John W.

Mike thanks for the image -- tangent_void_800_5.jpg I like the blue background brightening to almost an electric blue -- which then nicely highlights the arms of the "foreground" pattern. The dark collections of "holes" in the background hint that there is something else hidden behind the blue background, too. - Hal Lane ######################## # hallane(a)earthlink.net ####################### -----Original Message----- From: Fractint [mailto:fractint-bounces@mailman.xmission.com] On Behalf Of Mike Frazier Sent: Monday, September 7, 2015 12:49 PM To: Fractint and General Fractals Discussion <fractint(a)mailman.xmission.com> Subject: [Fractint] Tangent Void This fractal mixes tangent and z^2.

Re: [Fractint] I just ran across this fractal object: Hofstadter's butterfly:

Tony, > Any Fractint code for rendering this? I don't have any. You might try searching for Fractint-compatible code an non-Fractint program web sites (UltraFractal, etc.) I just tried a couple of searches (use the quotes to keep the two words together during the search): calculate "hofstadter's butterfly" code to calculate "hofstadter's butterfly" Since: ... "In physics, Hofstadter's butterfly is a mathematical object ... describing the theorised behaviour of electrons in a magnetic field." ... (Wikipedia) I'm not likely to be able to derive the equations myself... http://tinyurl.com/Hofstadters-butterfly-spotted or: http://physicsworld.com/cws/article/news/2013/may/15/hofstadters-butterfly-… gives a general overview of the calculation: "Hofstadter encountered a difficulty when considering electrons exposed to a magnetic field while moving in a 2D lattice. The problem lies in the fact that electrons respond to an applied magnetic field by swimming in circles at the cyclotron frequency. However, the orbital motion of the electrons is quantized in terms of a frequency that is defined by the properties of the crystal lattice. The presence of these two, often incommensurate, frequencies means that Hofstadter's calculation of electron energy levels yielded some bizarre results. Hofstadter tried to make sense of this difficulty by plotting the *wave function* of the electron versus a parameter related to the ratio of the two frequencies. The plot produced a stunning fractal pattern that looks like a butterfly."
