December 11, 2010: The Midas Untouch | Dec. 10 | Dec. 12 | 2010 | FOTD Home |
Fractal
visionaries
and enthusiasts:
Today's image takes us back to the MandAutoCritInZ formula, still the
most productive formula in my oversized and underused
collection. I named the scene "The Midas Untouch" because
sometimes every fractal I find seems to turn to lead.
Most of the effect of today's image is due to its coloring.
The sinuous bands that hold the golden colors were created by rendering
the scene with the outside set to 'tdis'.
The rather unlikely generating formula combines 8.4 parts of Z^(-2.2)
with 17.5 parts of Z^(-5.2) then adds (1/C). The parent
fractal is a shapeless thing with a large but disconnected minibrot
just southwest of the main body of the fractal, which is one of the
most twisted minibrots I have yet come upon. Today's scene
lies in the East Valley area of this minibrot.
The rating of a 7 makes the 47-second calculation time a
bargain.
Other bargains may be found at the following web

where the finished image soon will be posted.
Clouds moved in just after sunrise and hung tough here at Fractal
Central the rest of the day on Friday, tough enough for about 1/2 inch,
1cm of snow to fall in the afternoon. The temperature rose
from 16F -9C at sunrise to 30F -1C in the afternoon, assuring that the
small snowfall made things slippery. The fractal cats grew
bored watching snowflakes after a half hour, and spent the rest of the
afternoon in a warmer location.
My day was quite busy trying to clear away a lot of little nuisance
jobs. The next FOTD is due in 24 hours, but with the holiday
rush near its peak I will give no guarantee that it will be ready on
time. Until whenever, take care, and . . . .
