Hello fellow Fractronauts, thanks for populating this forum and its predecessor! I greet you from Hamburg, usually working from home when not distracted by our two cats – meanwhile a bit larger than on the photo.

Silent besides some bug reporting on Mandel Machine, I've sporadically visited for quite a while now – traces being my download of Pauldelbrot's "Mandelbrot Safari" back in 2012 or an email of 2013 in which I made Ultra Fractal's author aware of the perturbation method I had read about here. :)

But I've probably been reading much earlier once I had realised that newsgroups like sci.fractals were getting out of fashion. For those interested, and who might relate: When I got my first PC in 1991 (I think), a colleague of my dad's showed me "Fraktal Generator 3D" from 1988, which could render the Mandelbrot and Julia sets in both 2D and 3D using EGA mode – see the attached screenshot dating from today thanks to DOSBox. The speed of my 286 put my excitement to the test, but once I learnt about Fractint, I was hooked, although that, too, allowed all levels of slowness to be explored, especially once deep zooms became possible. I remember letting it draw a Lyapunov fractal for 18 hours in what was probably its great 360×480 mode with 256 colours, a resolution I considered sensational on my Standard VGA card that let me wonder why game developers stuck with 320×200. But I digress...and realise that such thoughts must make me appear prehistoric to some.

The only time I actually created a fractal generator by programming was also with Lyapunov, following a public lecture at a nearby uni in 1998. (At least if you don't want to count a PHP script to generate IFS-like text fractals where the letters are recursively composed of the whole word.) Beyond that, my experimentation was limited to using the formula features of Fractint and later Ultra Fractal. But I was usually more interested in deep Mandelbrot zooms, like this was the armchair version of exploring the universe, at least once Fractal eXtreme's 64-bit version reduced the waiting time. After the Perturbation Revolution, this was especially true, and I liked Mandel Machine the best, mostly because its default palette met my taste of intense colours and, addicted to the comfort of Ultra Fractal's gradient editor, I was frustrated by how that worked elsewhere. So when UF got to use perturbation, that was my call to buy a new PC – what else would you need one for? :)

My fractal creations are usually Mandelbrot zooms, either square or 2:3, not rotated, with a continuous iteration-based colouring (triangle-inequality average if I'm bold) and, again, a palette that looks like I needed to compensate for colour blindness. Perhaps I'll start slowly in the picture contest, though I'm a bit confused at there being two this month – one for "art" and one for "serenity"? I guess my purist approach rather fits the latter, though I need to pick one with a more conservative choice of colours...

Welcome!

That image brings it back for me, graduating from 16 to 256 colours was a milestone, and from 0.89 Mhz to 16Mhz was staggering. :beer:

edit: the image contests are: one with a topic chosen by the last 1st place winner and the other is open... I would have voted up the above image had you entered it  :thumbs:

It was possible to calculate 3D fractals on a 1MHz MOS6510 processor. It was just not a very good idea. :)

Yes, computers have come a long way. We are currently in a phase of rapid improvements again, after six or seven years of stagnation before. (Competition is a good thing, even if it leads to fanboi-ism and buyer's remorse.)

I remember back when I was little, before computers were personal, before it was clear I would own my very own computer someday, I already saw these machines as gateways into an abstract world full of new things to be explored. My view hasn't really changed since.

Are those your cats on the profile picture? If so, I like them! Welcome to the community!

Thank you! Yes, those are the two purring brothers that sometimes inject themselves in video conferences when I work from home. They were three months at the time, now they're almost seven. See the attached picture for their interest in the Mandelbrot Set. ;)

As for the earlier screenshot, I guess it would have had to be a very special context for me to dare enter it! But thanks, 3DickUlus, for clarifying that one of the two contests is just topic-less.

I can't really imagine how it would have been to tackle fractals with less than a MHz, though it was probably less annoying than it would feel right now. I once tried space-filling L-systems curves with a laser cutter – that was probably a similar speed.

...trying to change the ribbon on my dot matrix printer before the data for the next line got sent was even tougher ;)

but now we have fun games like this... Obfuscate the python, the image was created (except the text overlay) by the code in the image.

my my my, we've come a long way.
