Thank you indeed. Correct, I forgot about CC's plugin. When I have some 
time I shall dig that one up. Thanks for reminding me.

Cool scene, Thomas!

It's an intriguing shape to be sure, and I can't help but wonder if it's
possible to make it work for other Platonic solids (tetrahedron, octahedron,
etc.)

Are you familiar with tineye.com? You can upload an image or give it an image
link, and it will try to find other images on the web. It fails sometimes but,
when successful, it will find even higher-resolution images.

Thanks Sam!

Possibly yes; a hint for the L-systems gang? ;-)

Yes I am familiar with it but in this case it failed. Very strange...

It emits light.
Why ghost appears like that?

Maybe ghost looks more like a human...

Thank you.

I have found that it is hard to search.

To be more specific about the "ghost": it is not so much the media 
inside the structure which I named so in the subject's title, but rather 
the box-like structure itself which is a kind of 'non-box' which only 
'suggests' where the 'real' box should be. Difficult to describe this in 
words indeed; just try to visualise this in your mind looking at the image.
