Nice Find!  I never cease to wonder at what you can find exploring the M-set.

Nice image. The colors work really well. Care to give us the "specs?"

(image coords and magnification, and coloring method.)

It looks like you use some sort of log color scheme, since the color change gets smaller in the highest-iteration areas, thus reducing the amount of visual clutter.

Just for fun I tried to replicate this image. OK it's not perfect, but the idea is there, and it took me less than 5 minutes smiley
cheers!

Sorry, I don't have the coordinates or magnification.  I produced the image using my own program which doesn't provide these.

The color method is actually simple escape time  shocked

That is VERY close. What do the color numbers mean? Are those decimal equivalents of hex RGB triplets like 00FF00 for pure green? And what do the index numbers mean in the gradient? At first I thought they were iteration counts, but the numbers are not in order, and the last couple of values are negative.
