END OF AN ERA, FRACTALFORUMS.COM IS CONTINUED ON FRACTALFORUMS.ORG

Most people who are interested in fractals are familiar with how the shape of a Julia set echos the region of the Mandelbrot set it's taken from.

The reverse is also true. Hidden in the Mandelbrot set are little echos of Julia sets. The image below is not a Julia plot, but a standard Zn+1 = Zn + C mandelbrot set in the complex plain.

It's taken from a "baby Mandelbrot" on the real axis. I zoomed in to the "dragon" region of that baby mandelbrot, and then found a "grand-baby" Mandelbrot at the base of a dragon. I then zoomed in on a tendril just outside the "grand-baby" mandelbrot, and found the shape below, which looks VERY much like a Julia set.

The plot is centered on -1.6285474757381330, 0.0005260504563778, at a width of about 3.56E-10


Here's another example. This one looks like Fatou dust, but again, its actually a Mandelbrot plot.

This one was centered on -0.7702557119579104, 0.1130369146248582i. The width of the plot is about 2E-7.

pray tell, if you have these magnificently sized images, why don't you post gloriously antialiased ones online?

all it takes is opening the highres image in some decent image editing app, resampling (not ignoring every Nth pixel!) to the final res, and posting that. you'll notice a night and day difference... surely as a mac user you're well aware of antialiasing issues, since you use such a bling bling os all the time?

When I tried the link, it said "Diese Seite existiert nicht", which in english means the site does not exist.  Then it proceeds to give options for searching or creating it.
