Sounds a bit like saying "why pay for a car when walking is free"  shocked POV-ray makes absolutely horrendous quality and unrealistic images, and is sloooooow...

Indigo is free to use at <= 0.7 megapixels, and as I offered you in a note, if you'd like to render some prints (commercial use) at higher resolution I'd happily do this for you, if you'd like smiley I sent it to you in note because I don't want to spam too much here about Indigo, unrelated to the topic.

To Lycium:
No offense intended, but :
The image below consists of nothing else but 106,000 spheres.
Povray takes 3m18secs to render this at 768*1024 pixels (using radiosity).
Can Indigo do better?

Undoubtedly; POV-ray's "radiosity" also pales in comparison to fully accurate, spectral Global Illumination.

My suggestion here is with the view to make some really cutting-edge 3D fractal art. It doesn't have to be Indigo of course, there's always that other renderer I worked on, LuxRender!

since we're talking about photorealism already... How about physical realism? Get the 3D printing going cheesy (Though you'll probably need to reduce the details a bit, since the fragile parts won't work well with 3D printing as it stands today)

Does not 3D printing require a mesh as input?
I wonder how one can convert a colection of 700,000 spheres into a mesh?
Anyway, the detail of these objects is intriguiging, and it would be a pity to remove some of it.

Woow, it closely reminds some images of ABox, but there are some differences because the spheres are a bit differently arranged... A Beer Cup

I now have a small collection of such images at http://www.josleys.com/show_gallery.php?galid=346.
The article describing the technique is written (in French!), and should be published in about a month.
Contact me privately if you would like to see it before that.

The article on the subject is here http://images.math.cnrs.fr/Les-ensembles-limites-de-groupes.html.

Google translate should let you get the gist of it, but any silly translations are not my doing!
