Fractal
visionaries
and enthusiasts:
Yesterday's unusual scene in Seahorse Valley kept me thinking most of
the day on Saturday. In yesterday's image the Mandelbrot aspect
of the valley is totally invisible. In today's image however it
is visible in grossly stretched form as the open strip across the
center of the frame. If this open strip is stretched about 57
times in the vertical direction, the valley itself will become visible,
cut off on the E-W sides but decorated with all kinds of new and
unusual stuff. This can be done in the Z-f6 screen by setting the
X-magnification factor to 0.0175.
The orientation of the image is rotated one degree from the Oblate and
then rotated 45 degrees toward the Julia. All this rotation
happens in the 4th dimension, so don't try to make sense of it.
The name "Seahorse at Length" refers to the piece of Seahorse Valley
stretched across the center of the frame. I rated the image at a
6 because I did too little work on the coloring.
The calculation time of 16 seconds is no mistake, so there will be no
wasted time if the image proves disappointing.
A rather hot day prevailed here at Fractal Central on Saturday.
At least the fractal cats thought so. They spent most of the day
stretched on the cool tile floor. I also thought it was hot, and
spent the day within range of the cool air. Everyone I mentioned
it to also agreed that the high temperature of 93F 34C was indeed hot.
The day was busier than usual for both myself and FL as we wrapped up
the leftovers from the big rush job of the past two days. The
next FOTD will be posted in 24 hours. Until then, take care, and
stay decohered.
