Assuming that the Mandelbrot Set is black on a white background, I'm talking about surround a white space, not a black midget. I don't think that the Set cannot be a single line, as it also goes through midgets (areas) where multiple lines depart. Also, does the line to the west of the Mandelbrot Set include a limit, or does it approach a limit? I think it is the former, a truly calculated point, but I'm not sure.

Getting in over my head here, but it seems to me that if the MLC is true - and my understanding of the article is they are close to saying so - then it would be impossible to surround an interior lake, since the entire set would be a single line.

Lee Skinner has been having trouble posting. Here is his response:
The MLC (for *Mandelbrot locally connected*) conjecture in the article states that all points in the Mandelbrot Set are continuously connected to one another.
I have another conjecture of my own: *There are no closed loops in *(the "filaments" of)* the Mandelbrot Set*, i.e, there are no "*white* islands", but I am unable to formulate this exactly in formal mathematical terms. A white island would be an area of space not in the Mandelbrot Set, but completely surrounded by a portion of the Mandelbrot Set. My conjecture says that such white islands do not exist.
How do you even define a "visible filament", when it becomes something else entirely (and much more complicated) upon zooming into it? (Mostly, it is simply an *infinitely* long segment of the Mandelbrot Set between any two points of the set, however, picking the two end points of a visible segment is also difficult, as zooming into such a point also becomes a frilly design, unless, e.g., it is on the *finite* straight line west of the Mandelbrot Set.)

You've done it again! What an interesting read you've pointed us to.
The following snippet from the article in particular caught my attention in a rather personal way.
Back in the days when we were getting together on the GraphDev Forum using TapCIS and Compurserve, I was fairly involved with the evolution of the sound feature in Fractint. One discussion in particular (as I remember it, it was with Dan Farmer) had to do with what the fractals that I was using for my audio fractal files looked like.
For one thing, they don't look like they sound <s>. But the other thing is that most are generated using a sample of fewer than 1,000 pixels (some are fewer than 200) from the entire fractal image of usually greater than 1024x768 pixels. The audio files are generated using orbit delay values of usually greater than 500 (depending on processor speed) and maxiter sometimes over 500...i.e. to generate the full image while in audio mode would be very time-consuming. There is the additional other thing that since I am not at all interested in the image, just the sounds, the visual fractal is very often quite uninteresting at best and downright ugly most of the time.
I was asked why not just generate the fractal image "quickly" and then use the image as a sound map for the audio? The answer is that my audio fractals generate a HZ value for each iteration of the pixel calculation
often hundreds of tones per pixel - the "journey" - whereas generating audio from the image produces a single tone per pixel - the "destination" - and in no way sounds either like the audio file nor, IMO, "fractal ". In fact, I'm not sure one could distinguish the structural difference between the audio generated from a fractal image and a photograph of a street scene, landscape or family get together.
Thanks for indulging me - here’s the quote
***************** "(…We distinguish “pure math” from “applied math.”) The way math papers are written doesn’t help: Only the final proofs and theorems are usually published, not the meandering process that led to them."
******************
That hit home. For me, the destination is just the end of the journey, and usually quite anticlimactic. Sort of like life.
