Combination of Mandelbulbs:

0 itr - bailout
      th0 = asin(z.z / aux.r);
      ph0 = atan2(z.y, z.x);
Power 9 with z  = z + (cpixel * constant) ,      constant = ( 1, 1, 1)


with:

For 1 iteration
      th0 = asin(z.y / aux.r);
      ph0 = atan2(z.z , z.x)
Power 3 with z  = z + (cpixel * constant) ,      constant = ( -1, -1, -1);

Ray marching step multiplier  of 0.1 gives acceptable DE  (this is one of the good combinations in respect to DE)

I like these ones where you need only one iteration to  make all the difference ;D
 
For the last two years I thought Mbulbs were kind of  boring but now I find they are not ;D

Cheers
