Yes. The onion and spherical patterns come to mind.
In your case, I think that onion with a colour_map going from high to 
low would be better as you don't need to scale it as much : You can only 
take the 10000th repetition
  of the pattern if you want.
Next, add some turbulence, possibly adding some other pattern(s).

Don't forget to make your media sufficiently dense.
