Fraxious

Fraxious is a program which displays Mandelbrot, Julia, and a few other
fractal types. Currently, it runs only on PowerMac.

Overview
You create a fractal by choosing New and the fractal type you want from the
File menu. You are then presented with a dialog box of parameters to fill
in. When you press OK, Fraxious creates a window and generates the fractal
in it. You can adjust the colours using the Palette floating window.
You can 'zoom in' by selecting a portion of the currently displayed fractal.
Saving the fractal saves it as a PICT with some other resources, so you can
reopen it in Fraxious to continue generating or adjust the colours, or open
it in an image-editing program like Photoshop.
When you have two fractals of the same type open, you can create a movie
which 'moves between' the two fractals. For example, you could create a
movie between a Mandelbrot and a zoom of it; between two Julia Sets with
different real and imaginary parts; or between two Mandelbrot sets using
different powers of Z.

Fractal Types
Mandelbrot - mandelbrot set for Z^2 + c
Julia - Julia set for Z^2 + c
Newton - Newtons method for Z^n - 1
Henon Map
Strange Attractor
FM2D - Two-dimensional fractal brownian motion - good for clouds
General Mandelbrot - Mandelbrot with (fairly) arbitrary equations. Allows
expression with */+-^ operators and functions real, imag, abs, norm, arg,
conj, cos, cosh, exp, log, sin, sinh, sqrt, sin, sinh, sqrt, sqr, tan, and
constants e and ¹ (pi). For example: (Z/e)^c+sin(c) or ((c+e)^(z*c)). Be
warned - this is slow, as the equation is interpreted rather than compiled.

Bugs.
There are some bugs which cause the program to end unexpectedly. Please let
me know of any bugs you find, with details of how to recreate them.

Comments.
Please let me know of any improvements or any interesting algorithms to add.
Also let me know if you have found the program of any use.

This is freeware.
