I recognise the island. It the one mentioned in Shakespeare’s play, “The 
Tempest”.
“…’twixt the green sea and the azured vault...’ ;)

It is strikingly vibrant and unearthly.

How to animate it?
The only thing I can think of, is to find out how animated motion lamps 
work. They had a cylindrical outer and inner part and the inner cylinder 
rotated from the heat of the light. The outer cylinder had transparent 
areas that showed the motion. A quick google did not describe the technique.

You get a short glimpse of the moving part here.

It what is written? It is a Devanagari?

It is necessary to think. :)

No that is corruption. I am posting with thunderbird using Unicode. It 
should be plain English text.

Twixt the green sea and the azured vault

Twixt is old English for between.

Yes, me too.

I found these. The insides are shown. Look at the pictures.

I may be missing something here, but is animation not very easy? just 
rotate the inner cylinder. Essentially, the whole structure consists of 
two moving semitransparent, superposed, image_maps.

Probably not. But it is mumble, mumble years since I have seen one and 
was not sure how the effect was created. I thought that the glass 
cylinders might have been moulded to give local lenses on the inside.

Will the illusion work with computer graphics using planer images?
What sort of masking is needed for the images and what frame rate to 
use? These questions I will need to find an answer to.
I think that this might distract me from Elite Dangerous, for a while. :-)

Yes! Desires differ from opportunities...

Hmm... that is an interesting approach I had not thought about. Variable 
thickness of the inner cylinder might certainly be an interesting effect.

Good. It will keep you from grave mischief in the digital world. I may 
want to explore a bit about superposition of images and such, without 
the animation part. I think that ior and photons should be involved too 
in the end.

Proof of concept.
It needs more work on the inner cylinder* and the masking.
It is short and cyclic. Probably better to download it and watch it looping.

* Not that there are cylinders, it is planer.

This toy can be made so:

#declare Light_waves = texture {pigment {
    agate
    color_map{[0 rgbt<1,1,1,0.9>]
              [1 rgbt<0,0,0,0.9>]}
    scale <1,10,1>
    translate -z * ANIMATION
}
}

#declare All = texture {
    texture {Sea}
    texture {Light_waves}
}

My idea more serious:
1. Create curves.
2. Insert shape keys
3. Use LanuHum,s exporter.
Good?
