Fractal
visionaries:
Since it is a weekend everywhere and a holiday weekend in the USA, not
many will be sitting in front of their computers when there's so much
more to do outdoors. But for those who spend holidays inside
searching for fractals, here's a striking one.
A week or so ago I saw a message on sci.fractals, (I believe it was
from Jon), asking if anyone had done much work with Z^Z and Z^(-Z)
formulas. I have done a bit of work with this type of
formula. In fact I've made exponent towers of various
combinations of ^Z and ^(-Z) up to 12 levels high.
The resulting images are always filled with discontinuities and
fragments of various shapes. Often they are too chaotic, with
no center of attention, but sometimes the fragments join together into
a pretty good picture. Today's fractal is one
of those good ones, where the floating fragments and big blocky squares
make a reasonable picture.
Today's formula is loaded with possibilities. With all the
variables to play with, one could spend a lifetime and not see >
all that this formula has in it. And I've got a couple dozen
variations on file.
For tomorrow, I've got a most unusual Newton image waiting.
