erupting colors

Fractal visionaries and enthusiasts:

Today's image rates a 7-1/2.  Because of its excess busyness I could not rate it at an 8, but I did award myself an extra half-point for the colors.  Extra color work was necessary.  For some reason, this particular image is unusually difficult to color.

The generating expression is the same as yesterday's, but with the absolute value of the second exponent of Z lowered from -5 to -0.5.  This change clears most of the debris from the main bay of the underlying Mandelbrot set of the parent fractal, while at the same time eliminating much of the original Mandelbrot outline.  An obvious minibrot lies at the northern edge of the remaining main bay.  Today's scene lies in the detail surrounding this minibrot.

The name "Erupting Colors" indicates that I consider the colors a bit too gaudy.  The calculation time of 4-1/3 minutes is too slow to be a bargain, but the calculation can be avoided by visiting the web sites.

A near perfect May day prevailed here at Fractal Central today, with blue skies, lots of sun and puffy white clouds.  The temperature of 72F 22C kept the fractal cats, who are totally indoor cats, quite satisfied.  The humans meanwhile had another nondescript day, which needs no description.  The next FOTD will be posted in 2 days unless an antiquing expedition planned for tomorrow is cancelled, when the next FOTD will appear then.  Until whenever, take care, and one man's good may be another man's evil.
