From what we envision from the Zembla perspective, arises the
virtual image with the label "Pale Fire" ( it works the other way round,
too).
At the same time that we see the marble, we also find its reflection on the
silvery surface it is resting upon ( unrelated to the other 3D phenomenon).
The black cover of the gadget, itself another kind of reflecting
surface, informs the viewer about various external interferences
( such as ceiling lamps) which are also to be found on the
silvery surface while we meet other external objects that are not above (
as the lamps) but below, on the table where the "Mirage" gadget is resting.
This image is a visual rendering of only a
small part of what me may find when we read "Pale Fire", illustrating
various kinds of mirror-effects that only double an object, but which might also
recreate it in a "virtual field" that seems to be "outside", but it also carries
"interferences" that might ( or might not) reveal other elements that sustain or
mingle with the original "object". This is only a game. Words and
VN's sentences in particular are a hundred times richer than
that...
