2 quaternions rendered in
Pov-Ray. Nested & scaled one at 9 iterations the other at 10.

It came out very good!!!     :D
At first, because of the two color offset, I thought it was an Anaglyph 3D.

Need to get me a pair if 3d specs !
something to try later.

A couple of ideas I want to follow up on are rendering quaternions - keeping the iterations the same this time
but scaling them down inside each other like a Russian Doll using coloured glass materials.

Also trying some boolean subtractions with a cube to see what cross sections look like  :)

I did quite a few cross sections a few years ago, slicing off different amounts to see what would show up inside.  Got a few renderings that were very unique and interesting.  Definitely was worth exploring.  I will be looking to see what you produce.     :D

Created a couple of Pov Ray files.

Nesting quaternions inside each other

I think there may be problems with Co-incident_Surfaces - lots of black triangles.

Have been experimenting with using a clipping plane as it has less artifacts.

Heres a .pov file if anyone wants to have a look

Low iteration to high iteration, while moving the clipping plane closer to the camera with each quaternion instance. - New shapes by changing variable "ConstE"

couple of renders here.
