Extract-a-Mandel 2

Description: A different coloring applied to my algorithm that extracts, or "explodes", mini-brots out of the main Mandelbrot set through dynamic rescaling. Each little island has mini-brots. The simple formula is:
______________
int g = 0;

ct_complex jp[2] = {
    { .04, .07 },
    { -.04, -.07 }
};

for (unsigned int i = 1; i < 123; ++i)
{
    z = z * z + c;

    // escape condition
    if (z.real() * z.real() + z.imag() * z.imag() > 250)
    {
        if (g < 16)
        {
            z *= (i % 2) ? jp[1] : jp[0];
            ++g;
            continue;
        }
               
        return; // escaped, so bail!
    }
}

// did not escape...
______________

Actually, it is quite fast wrt getting at the mini-brots.
