Filmmaker François Vautier put an ant colony inside a scanner and took a picture once a week every week for five years. This time-lapse video shows the colony gradually filling and eroding the machine.
"...an equilateral triangle has three sides all the same length. An isosceles triangle doesn’t (the hypotenuse is longer)..."
Sorry, that's not correct, unless the isosceles triangle also just happens to be a RIGHT triangle (the hypotenuse is the side opposite of the right angle). An isosceles triangle is simply a triangle with two sides of the same length (an equilateral triangle is also an isosceles triangle, incidentally).
The Mandelbulbs seem to be the latest trend lately in the Fractal World, just as the flame fractals and Apophysis were a couple of years ago until they were overused by these people at Deviant and their random renders (now every flame fractal looks the same - boring! With a few exceptions of course). As a Fractint fan... I still didn't find that much fun in these Mandelbulbs yet. I had more fun with the simulations of Vision of Chaos (the buckets, the ants looking for food leaving trails of pheromones and the fish vs. sharks are amazing), and its "Genetics" sections as well.
Dear Editor, I don't know why did not you mention my name, when you mention spidrons, I was working on it for 30 years and trade marked two years ago. You can see much more on spidrons and the newest development: sphidrons best regards, Daniel Erdély

If there wasn't the description of ants and a scanner, I would have had no idea what was happening.
In the Mandelbulb paragraph, there's a "#D" where I think you meant "3D", but that's a minor quibble. Great article!

Btw, "isosceles" just means that at least two sides of the triangle are the same length--the third could be longer, or shorter, or even the same size.
So, you could have a very wide angle between the two same-length sides (as in your spidron) or
the angle could be very narrow (think of the top part of a capital A)
or they could all be the same length--every equilateral is also isosceles.
(But *not* every isosceles triangle is equilateral--just as every square is a rectangle ie, has 4 right angles, but not every rectangle is a square.)
