"Rudy Set" as Ultimate Cubic Mandelbrot Set. Quartics & Quintics, too!

* On May 4, 2010, I began selling art prints of these images at my Ultrafractals gallery at rudy.imagekind.com.

* On May 3, 2010, I added some more Cubic Rudy Set images, and I started claiming that the Rudy Set is the "true" or "ultimate" meta-version of the Cubic Mandelbrot set.

* On April 22, 2010, I began adding some movies of these fractals to my rudyrucker Youtube channel.

* On April 7, 2010, I expanded this post to discuss the Quartic and Quintic Rudy sets.

The Rudy Set is the TRUE Cubic Mandelbrot Set

* Fun with fractals starting on April 2, 2010.

* On April 7, 2010, I expanded this post to discuss the Quartic and Quintic Rudy sets.

* I've been adding some YouTube movies since then, most recently on April 22, 2010.

* On May 3, 2010, I added some more Rudy Set images. This, of all the fractals I've mentioned here, seems to be the best one. In short, the Rudy Set (or the TRUE Cubic Mandelbrot) is the the set of all c such that the cubic Julia set Jcc is connected.

Cubic Mandelbrots and The Rudy Sets

Fun with fractals today (April 2, 2010)…and on April 7, 2010, I expanded this post to discuss the Quartic and Quintic Rudy sets.

I gave an early version of this post as a talk at the Computer Systems Laboratory Colloquium Stanford University twenty years ago, on March 7, 1990, as "Computing Sections of the Cubic Connectedness Map." The hardware designer John Wharton invited me. Some of this information also appeared in the manual for the James...

The Rudy Set Fractal

Fun with fractals today!

I gave an early version of this post as a talk at the Computer Systems Laboratory Colloquium Stanford University twenty years ago, on March 7, 1990, as "Computing Sections of the Cubic Connectedness Map." I think John Wharton invited me. Some of this information also appeared in the manual for the James Gleick's CHAOS program.

As I was discussing near the end of my previous post, CHAOS is unusable on the newer versions o...

What is a Chaldron? (And Other Stuff)

So I'm well now. Thanks, all, for the kind wishes and the birthday greetings.

I've been taking a lot of photos lately, so today I'll just run some photos with some recently arrived links, some remarks about the current state of my free software…plus a discussion of Jonathan Lethem's Chronic City with a particular focus on the question, "What is a chaldron?"

My artist friend COOP told me about a site with information about Kanegon—if you scroll way down on the page linked to, you can find...

Life Goes On

So I'm all well now. Thanks, all for the kind wishes and birthday greetings.

I've been taking a lot of photos lately, so today I'll just fill in the text with recently arrived links and/or with mini-reviews.

My artist friend COOP told me about a site with information about Kanegon—if you scroll way down on the page linked to, you can find some video of Kanegon, who's played by a guy in a rubber monster suit with a kind of garbage-can-top head mask.
COOP sent me a great photo he took of his...

Hearty Paintings By A Million-Year-Old Man

As of today, March 22, 2010, I'm 64! This is two-to-the-sixth-power or 1000000 in binary, or, as my old mathematician/computer-scientist friend David Slater puts it, "one million base two."

Speaking of feeling like I'm a million years old, about six weeks ago I started having a pain in my chest when bicycling up a hill or even climbing steep stairs.

My doctors gave me a series of increasingly ominous exams...

Mapping the Gnarl

I found an interesting page that creates a free map of a website on the fly. The applet was made by an energetic Stanford grad student named Marcel Salathé. Here's a map of www.rudyrucker.com/blog. Those "flowers" at the top left are the individual posts on the top page of my blog which is, I think, the main page that is being mapped. That dandelion of yellow dots is, I think, for the comments boxes.

I got curious about website maps this morning because a 78-year old lady from the Pacific ...

At Loose Ends

I feel odd now, between books. Like I just got out of the pen. (Pun!) Or out of the cave. Trying to relax, to slow down the art factory machine. I should be paying attention to the world while I can. Enjoying it. Doing nothing. It's surprisingly hard, that.

I spent one evening listening to some of my old vinyl records. I came across a great oddball pscychobilly LP, Destination Zululand, by a group called King Kurt.

And I'm taking a few pictures (like those shown today) with my new...
