Another view of the same scene.

Another render. This one also transitions between fractal powers (squared to cubed).
#fractal

Morphing fractal shapes.

This is a Julia fractal with a linear interpolation of the distance function between iteration counts. Starts by interpolating between 1 and 3 iterations, then 3 and 5, etc...
The material also changes for no particular reason...

I tried a quick animation, but again it's missing a big part without the caustics. This is moving the income ray very slightly left and right.

Fly-through for better context.

The rainbow is still elusive...
But how about subsurface scattering the hard way? By rendering tiny diffuse particles (atoms?) to simulate the many internal bounces of the surface.
Looks a little bit like sugar.
