Same formula as yesterday’s Sequence Fractals Part V #14, different neighborhood.
The orange blob looks like a distorted cubic multibrot. But there is nothing cubic in the formula. The exponents are 5/2, 1/2, -3/2. Seems unlikely, but perhaps the 3 in the numerator in the third exponent is doing it. I think the area surrounding the orange spot looks like ice crystals forming on glass on a cold winter night.
