  Not yet. I'm a perfectionist and I would like a precise formula
(like z(n+1) = z(n)^2+c) instead of a trial-and-error-trying-type waving
of hands formula.

: How about the various z functions (sin, cos etc.)?

  Like the julia_fractal uses? Perfectly possible. I just have to think about
a way of doing it that minimizes typing work.
  It might not be impossible even to use a user-defined isosurface function.
However, I will probably wait for pov3.5 for that.

: could consider adding it, too. There's a detailed explanation in the
: FractInt help.

  Isn't the Julibrot just the julia_fractal already as an object in povray?
That is, the regular julia set but using hypercomplex or quaternion numbers
instead of complex numbers.
  It shouldn't be hard to make some modifications so that the current
julia_fractal could also be used as a pattern. I have to look at it.

: See? Someone else cares :)

  Thanks :)
