Cube roots of 'j' by MakinMagic

This is just an imperfect example of a 3D quaternionic Newton - in this case for the cube root of (0,0,1,0) where the 3 axes used are r,i,j from (r,i,j,k).
The colouring is one layer of orbit traps (trapping r and i) and one layer of lighting.
It's solid at 30 iterations and this is the actual render size - it's difficult/slow to render Newton fractals accurately in 3D
