A 2D fractal based on a modification of Tglad's Mandelbox formula, and colored using an algorithm I did some time ago called "circleboard".

Here it is (Ultra Fractal):

Circleboard {

init:
  float zzr = 0.0
  float zzi = 0.0
  float rr=0
  float ri=0
  float m=0
loop:

final:
zzr=real(#z)
zzi=imag(#z)
zzr=zzr/@scale
zzi=zzi/@scale
zzr=zzr-floor(zzr)
zzi=zzi-floor(zzi)
zzr=abs(.5-zzr)
zzi=abs(.5-zzi)
#index = sqrt(zzr*zzr+zzi*zzi)*10

default:
  title = "Circleboard"
  float param scale
    caption = "Circle scale"
    default = 1.0
  endparam
}
