Fractal visionaries and enthusiasts:

Today's image shows a normal minibrot in the upper left and an anti-minibrot in the lower right.  It's rather rare to find such an evenly matched pair this close together, so I had no choice but to color the scene and declare it FOTD for September 9.

The name "Negative Minibrot" describes the image pretty accurately.  The rating of a 7 is based mostly on the mathematical interest.  I put little effort into the coloring.

The calculation time of 1-3/4 minutes is well within reason.

The wind was a bit blustery here at Fractal Central on Wednesday, but everything else was near perfection, with brilliant sun, only a few small cottonpuff cumulus clouds, low humidity and a temperature of 81F 27C.  The fractal duo of cats enjoyed things to the fullest.

My day was satisfactory.  FL's day was pretty good also, though she really could use some rain on her gardens.  The next FOTD will be posted in 24 hours.  Until then, take care, and not only will technology be unable to save us, it might actually be our downfall.
