Talk:Hollow-Face illusion

I've removed the following section:


==Why it works==
It works because you can't see a 3D image on a 2D surface (e.g a computer screen), so your brain cannot tell which way the face is pointing.


because the illusion works also in 3D, not only with a picture of the item, as is also said in the text above.

Moved Original Research to Talk Page

edit

The following text has been moved from the main article:

(Barlow (1997) takes a more ‘reductionist’ view preferring to think of this in terms of redundancies of bottom-up signals from the eyes. I would limit this to very general features, such as properties of edge-signalling giving contrast effects, rather than phenomena attached to particular objects or particular classes of objects, such as faces.)

Inverted box

edit

I've seen an advertising variation on this illusion involving a small product box attached to a poster. The box appears cuboidal but is actually inverted, and in distorted perspective, so that it appears to float in mid-air and rotate as you walk past. Unfortunately I can't supply photographic examples, though I'm sure anyone with a modicum of skill and some cardboard and glue can re-create the illusion for the amusement and edification of their friends.

Removed even more original research

edit

Riddled with grammatical errors and such, this little gem of unverifiability is as follows:

It was created by the sculpture Enrico Filiberto Cerracchio. The original casts are held by his descendants, the O'keefe/Bates family of New York. The first example is that of the face of Jesus. The manner in which Cerracchio lost the rights to this creation is one of debate, but the dating of the casts proves the earliest example of this technique.

I couldn't find any mention that Cerracchio has ever used this technique, let alone that he invented it. Perhaps the O'Keefe and Bates families should have a historian or two verify their original research before they post it to Wikipedia. And... "The face of Jesus" is the first hollow-face illusion? Some dating proves it too!

Animation not so great

edit
Full-rotation version
Alternating version

The animated demonstration currently in this article is not the best example. It is less effective because the axis of rotation is off-center. This makes the illusion less dramatic 71.185.45.137 (talk) 21:09, 3 February 2022 (UTC)Reply

  Done I've made two new animations fixing the above issue. Which is better? cmɢʟeeτaʟκ 20:20, 28 March 2022 (UTC)Reply

Stupid "illusion" can be used to test stupidity

edit

This "amazing illusion" is just a moronic stunt. Anyone with some analytic abilities will see that the shadows on the "concave" side are exactly like the ones on the "convex" side, which shouldn't happen if a real mask were turned like that. 82.76.117.167 (talk) 10:44, 8 April 2023 (UTC)Reply
