I'm not really sure of how you get from an on/off landscape to a fractal landscape - or, indeed, if the concept of landscape is relevant.

What the rule seems to me to be, is that organic shapes are cuter than geometric. Cuter ensures hormonic reinforcement.

What I would like to know is: yes, I can understand the geometric tracery of the lines that connect points in XYZ, but are these colours generated by the data or by some arbitrary human overlay?

I was about to say: "there are few emotionally valuable geometric concepts in two dimensions." But that's when I understood the paradox.

The visual example you produce is, in fact, fine embroidery on black velvet - known from the traditional clothing of the Finnish roma.  Now  THAT'S pretty cosmic. <in my mind>

You can't be me, I'm taken

If it persists see a doctor. It could be a bad case of heartburn but the worst case that springs to my mind is a haital hernia, which can be fatal. I knew someone who almost died. He thought he was having a heart attack. The link may help you sort out things.

As the Dutch said while fighting the Spanish: "It is not necessary to have hope in order to persevere."

So what's the connection between magnesium and muscle cramps? Think of a key and a lock. Normally stored in muscle and bone, magnesium acts like a key that unlocks muscle cells, allowing potassium and calcium to move in and out when needed as a muscle does its job.
Without adequate levels of any of these three nutrients, the muscle becomes irritable, says Dr. McLean. "It's a crude analogy, but to keep the muscle cell adequately healthy and alive, you need to get potassium into the cell, and you need to have magnesium to open up the door to let the potassium in," he explains.
Make no mistake: Both potassium and calcium are also vital to this process. It's just that the body generally has adequate amounts of these two electrolytes on hand, says Dr. Brilla. If the body is going to get low on any electrolyte, it is most likely to be magnesium, she says. Doctors have long marveled at magnesium's powerful relaxant effect on muscles. In massive intravenous doses, this mineral is the preferred treatment for stopping premature labor contractions and a dangerous condition called preeclampsia, which causes extreme swelling and high blood pressure in pregnant women. (Note: Pregnant women should not take any supplement without first discussing it with their doctors.)
Before recommending magnesium supplements to ease muscle cramps, Dr. McLean does a blood test to determine an individual's blood magnesium level, to make sure that it is not unexpectedly high. If the blood level is low or even normal, then body magnesium stores may be low. Unfortunately, a normal blood level does not ensure that body magnesium stores are adequate.
Based on the results of the tests as well as the person's muscle cramp symptoms, Dr. McLean usually recommends taking one 400-milligram magnesium capsule two or three times a day. "I wouldn't go higher than that, because too much magnesium can cause you to develop diarrhea," he says. (Magnesium salt is the ingredient that makes Phillips' Milk of Magnesia, a popular bowel cleanser, do its job.)
But be careful: If you have kidney problems, taking magnesium supplements may make you accumulate the mineral too quickly, which could be toxic, says Dr. McLean. If you have kidney or heart problems, you should check with your doctor before taking magnesium supplements. Some people taking magnesium may get relief from leg cramps right away, but a long-standing deficiency can take weeks to overcome with supplements, says Dr. Brilla. "We like to recommend supplementing for four weeks," she says. "That's how long we feel it takes before we have some kind of measurable outcome."

Magnesium - a natural remedy for muscle cramps
Canadian doctors have found that magnesium supplements can alleviate muscle cramps. In severe cases, magnesium has been provided intravenously and this has led to relief of symptoms within 24 hours. Many cases of muscle cramps are caused by low concentrations of magnesium in the blood which can be the reason why it helps is be due to diuretic medications or strenuous exercise. When taken orally, it seems that magnesium glucoheptonate or magnesium gluconate work best.
