And I mean *really* deep:

  Years ago I asked here the question: "If you zoom enough into the
Mandelbrot set, will you finally find the Truth?"

  If you watch that fullscreen from start to finish, with sounds on,
maybe you will.

That is deep!

I can't say I appreciate or like the music.

Thanks for posting, I like the 3D version. :-D

  It's not a question of liking it. It's a question of feeling it.

That's as deep as the zoom ;-)

Very cool. Altho I'm not quite sure what his comment about the speed of 
light is supposed to mean. :-)

I find it interesting that at the beginning of the movie, it zooms into 
largely repetitive areas of the fractal (fringe areas where very similar 
features are repeated over and over next to each other), and then for 
the last two thirds, it zooms into one specific point of interest. 
During the second part, you can see wheels with spokes, and the number 
of spokes increases, slowly at first and then very quickly until the end 
(which I won't "spoil" for those who haven't watched it). It's as though 
bypassing all the repetitions in the first part is "winding up" 
complexity that has to be "unwound" by zooming very deep into the 
concentric circles in the second part. There's probably a mathematical 
explanation for this.

That is really, really deep. Everything a look at now appear to be 
receding away from me.

It's also very pink. I don't know what this was rendered with, but it 
seems to have a 256-colour limit, meaning that the colours repeat a hell 
of a lot. I did a zoom not unlike this using POV-Ray. Obviously the AA 
is all over the place, but it does mean I have unlimited colours, and I 
can map them as I see fit.

The location chosen is very, *very* repetitive. I mean, really, if you 
watch the first minute or two of the video, you've now seen everything 
there is to see for the entire 10 minute marathon.

Ditto for the music, actually. It's just a drum beat with some 
occasional accompaniment. I like trance music, but this is the kind of 
thing I'd routinely skip over. There's just too much drum and not enough 
notes. I also find it kind of interesting that I'm gazing at pristine 
mathematical perfection while listening to distorted gurgling electronic 
grunge.

Of course, what I'd really like to do some day is do a long fractal zoom 
(or more likely a succession of them), and spend time tweaking all the 
colours to the exact details of the fractal, and build some sort of 
soundscape that complements each feature of it. Sadly, I am drastically 
incapable of synthesizing such a transcendental fusion...

That's what I thought too.  It reminded me of the old FractInt, which, 
by default, saved to .GIF so it was limited to 256 colors as well.

*Googles*

Holy crap!  FractInt is still maintained!  There goes today's hope of 
doing actual work.

What, you didn't know that? ;-)

I used FractInt to produce all my stuff on Zazzle. Still, I keep meaning 
to put together a "real" fractal renderer one of these days. One that 
can handle 48 megapixel images without having to render them as 
two-dozen GIF images rendered in a framebuffer that has to fit inside 
"conventional memory" (!!) and then stitching them together into a giant 
50MB GIF file. It's really slow...

  Naturally POV-Ray won't cut it for such a deep zoom because it will
start glitching out at about 2^50 zoom factor (because 'double' only
has 53 mantissa bits). You need a software with multiple-precision
floating point numbers (or such a library, if you want to write the
program yourself). Of course rendering such deep zooms with such a
library will be slooooow (because software floating point is very slow,
and the amount of iterations required for such zoom levels doesn't help
the matter either).
