FOTD -- April 24, 2010   (Rating 8)

Fractal visionaries and enthusiasts:

Today's image is an imaginary scene near the edge of a huge volcanic eruption on an alien planet.   The generating formula, 'escher julia' is one of the lesser-used ones hard-coded into the FractInt program.   In fact, I think this is the first time I have used it as the source of an FOTD image.

The formula generates pseudospherical fractals from Julia sets of the Mandelbrot set, in which the Julia elements are repeated ever smaller as the edge of the circle is approached.   Today's scene, based on an East Valley Julia set, is located at center-bottom of the parent circle, where the Julia sets are divided quite small.   Of course, as in all fractals, there is no limit to how much smaller and more numerous the Julia sets become.

The rating of an 8 includes one full point for the effort I put into the coloring.   The name "Infernal Eruption" needs no explanation.   The calculation time of 1-1/4 minutes will bring palpitations to the heart of the true fractal fanatic.

Another way to have a leaping heart is to visit the FOTD web site at:and view the finished image there.

Another totally perfect April day came and went here at Fractal Central on Friday, with clear sunny skies and a temperature of 66F 19C.   But the weather experts tell us that Friday was the last perfect day we will see for quite some time.   This worried the fractal cats not one bit.   My day was average; FL's day was the same.

The next FOTD will be posted in 24 hours.   Until then, take care, and why, in our mind's eye, can we so easily remove all objects from the universe and imagine a vast emptiness, and yet be unable to remove the empty three-dimensional space?
