Dear XYZ,
My name is Akiyoshi KItaoka, one of the committee members of Visiome Platform.
The dragon illusion is one of the commercial creations of Grand-Illusion.com.

In general, this kind of illusion can be called “reverspective”. There are
at least two types of reverspective. One type is a trompe l’oeil which uses
line perspective, e.g. the Ames trapezoid, Patrick Huges’ artworks,
or my production shown below. Usually, “reverspective” refers to
this type.

"Illusory cube"

This physically concave object tends to appear to be convex.

The other type is called ‘’hollow face illusion”, a phenomenon that a concave mask appears to be a convex face.
This illusion is thought to be specific to face percpetion.

I imagine these two types of reverspective cooperatively play a role in the dragon illusion,
though I do not know any research articles which discussed this point.
Best regards,
Akiyoshi
