Fractal of the Day

Fractal visionaries and enthusiasts: For some strange reason I saw an airplane (aeroplane) propeller in today's image, and immediately named it "Propeller". Yes, I know that the prop would never work. With its caterpillar-like decorations and different-sized blades, it is so unbalanced that it would quickly shake the plane apart. But I think that this is the first time I have had a propeller come to mind while meditating on a fractal. And not a bad fractal propeller it is. By itself, the fractal image rates a 6, but I have given it a bit more coloring effort than usual, which raises the rating to a notably above-average rating of a 7. Much of the image's effect is a result of rendering the scene with the outside set to 'real'. (The normal 'iter' setting produces a far less interesting image.) Other than having the outside set to 'real', and putting a bit of extra effort into the coloring, nothing out of the ordinary was done with the image. It is obvious that the parameters of the parent fractal are a play on the square root of 2. The parent fractal itself is a mis-proportioned Mandeloid with a field of disconnected chaotic material scattered to its southwest. Today's scene is located in a tiny bit of cast-off debris lying deep in the East Valley of the main Mandeloid. The image renders in 5 minutes on my 10-year-old machine. This render time will be closer to 2 minutes on the more modern units, at least on those that are capable of rendering Fractint parameter files. Those with Fractint-challenged computers can still see the image by downloading it from the FOTD web site at: Sun and clouds, lower humidity, and a temperature of 86F 30C were just what the fractal cats needed to keep them happy on Wednesday. (Fractal cats demand happiness.) As a result, they spent over 6 hours enjoying hiding in the brush. They came inside without complaint as dusk fell, to enjoy their treat of tuna. Today is starting cloudy and much more humid. Flood warnings are in the forecast. I'm glad the repairs to the fractal basement drain have worked, and the basement no longer fills with backed-up water in heavy rain. But the cats had best do their Thursday exploring before the rain sets in. For me, it's the usual work-first-fractals-second kind of day coming up. The next FOTD will appear in 24 hours. Until then, take care, and if the earth was seeded with life from space around 3,800,000,000 years ago, how did the aliens who seeded the earth with life come into being in less time than the 10,000,000,000 years or so the universe had been in existence at the time of the seeding?
