It emits light.
Why ghost appears like that?
Maybe ghost looks more like a human...

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.

Ha ha...
I can't feel the mathematics trick (shape) is an unusual thing now.
