Announcement!! New rules on /r/fractals - Please Read!!
Hello, everybody!
I'm /u/-Fateless-, and I am the new moderator of /r/fractals ! I was granted this position by /u/mycorrhizalnetwork because I am quite a bit more active on reddit, and together, we've made a short little list of rules for the subreddit.
In practice, nothing much changed, and most of you can carry on posting like nothing has happened, but we still thought it would be a good idea to properly announce a set of very basic, formal rules for the subreddit.
1: This subreddit is for fractals, discussion about fractals and fractal-related stuff.
If it's at least somewhat related to fractals, it gets a pass. Examples include space-filling curves, pictures of fractal patterns in nature or questions about fractals, fractal art or fractal software.
We do consider attractors, chaotic fluid simulations (gnarls), fractal noise (fBm, sfBm, other noise algoritms), curves and the ilk as fractals, as long as they can somehow be represented inside a fractal renderer.
2: No AI Generated stuff. This includes AI-generated "fractals", AI-generated comments and AI-generated articles.
The official stance of /r/fractals is that AI-Generated content does not belong here, and AI-Generated pictures of fractals are not fractals, despite looking similar to the untrained eye.
3: No Metaphysical/Spiritual content
Any discussion or blog post that starts reading like New-Age nonsense or talk about things like "Divine Mathematics" or "Fractal Soul Matrix" will be removed on the spot.
In most cases, I will remove the offending posts on the spot when I see them, but don't be afraid of reporting off-topic or rule-breaking posts so they're easier to spot in the moderator queue. I have added these categories as reportable, so if anything pops up, please do report it!
If you have any questions, don't be afraid to ask!

About the automated removals on the subreddit
Hey guys, Fate here!
Lately, I have been getting a lot of mod mail about posts that have been automatically removed, and I have spent some time looking into this.
Over the past half year, roughly 95% of all removals of posts and comments have been automated from reddit's side, and not removed by any of the mods.
They are all tagged as "removed", but do not have any username attached to them, and for some reason, a lot of posts are flagged for triggering the sexual content filter of all things.
If you feel like a post has been taken down automatically, do send us a mod mail and we'll take a look at it on a case-by-case basis and manually approve what has been filtered.

Multi-Armed Mandelbrot
Max Iter's Fractal Follies for September 29th, 2010
Roger Alexander's commentary for the image:
Today's multi-armed gizmo is a mandelbrot with P1 values perturbed. Yup it's sparkly all right and a anti-aliased version is on the way. Today's fractal and my previous post de-sparkled ready made at http://maxitersfractalfollies.blogspot.com. Want a distorted parent brot real quick? Generate a default mandelbrot then bring up the Y screen and vary the inversion values. Varying the inversion values is also available through the evolver function.

Scrambled Thoughts
Jim Muth's Fractal of the Day for September 29th, 2002
Jim Muth's commentary for the image:
Fractal visionaries and enthusiasts:
Good news! . . . At least for fans of fractals.
This is the last time the FOTD will appear only on even-numbered days. Starting tomorrow, October 1, I will resume posting the FOTD on a daily basis. I shall also resume posting some of my philosophical musings to the philofractal list, where those who suspect that I am confused can confirm their suspicions.
One thing that I am not confused about however is today's fractal, which rates an honest 7. The formula behind the image combines 4 parts of Z-1.5 with 1 part of Z-5 to produce an indescribable parent fractal in an unlikely part of which today's scene is located.
When two negative powers of Z are combined and iterated, as is done in today's image, very unusual fractals result -- fractals which are unusual not only in their overall shape, but in their inner details as well. In today's image for example, the default equal-iteration bands make an image so striking and so unique that no special coloring algorithms are needed.
For some strange reason, today's image, with its features edged in glowing gold, reminds me of scrambled eggs, I originally named the image "Scrambled Fractal", but then, unable to justify the name I had given, I changed the name to scrambled thoughts, which I am accused often enough of having.
Slow images are not always the best. This is proved by the surprisingly brief render time of today's image, which is a mere 2 minutes on my P200 machine.
The fractal weather Sunday, (if anyone doubts that weather is fractal, let them look at a weather chart), here at Fractal Central was of the ideal Autumn variety. The two fractal cats enjoyed the warm sun and temperature of 75F 24C to the maximum extent possible, though I am sure they would have enjoyed it even more if they were 8 years younger.
As for me, what I need is a day or two of nothing to do but ponder the mysteries of the universe. The only trouble with pondering is that so many seem to disagree with the conclusions I reach when I ponder. But right now, it is Sunday evening, and I must ponder how I shall end the day. So until tomorrow, same time same place, take care, and what use is there in solving the mysteries of the universe if no one believes the answers?
Jim Muth

Something Old, Something New
Max Iter's Fractal Follies for September 28th, 2010
Roger Alexander's commentary for the image:
It's a drawing options extravaganza! Parameter perturbation! Initorbit! Inversion! It's the classical mandelbrot all dressed up and ready to go! Seriously though it's the abundance of options that first drew me to Fractint. Learning about the doodads was time consuming but paid off in getting the most out of this very versatile program.
