The left page of an open book contains incomprehensible text. The right page of an open book contains incomprehensible text. A closer look reveals a small dot on the bottom middle of each page, each with a small arrow pointing towards the other.
By looking through the book and aligning these
two dots in your vision, the garbled text on the overlapping pages springs into focus and stays in focus as long as your eyes stay unfocused.

It would be great if this stereoscription were an otherwise ordinary text, message buried within. |
|
| |
I often had this experience while reading Remeberance of Things Past. My eyes would blur and my mind would create exciting text content in the fog. Akin to sensory deprivation halucinations I suspect. |
|
| |
Are you suggesting that we would enjoy a whole book of these exciting illusions? |
|
| |
I offer no suggestions...only musings, and after trying out [Amos Kito]'s link I think that each book should come with a bottle of Aspirin. |
|
| |
I just tried to make this work, I think. The idea at its simplest, as I understand it, is not a stereogram, just missing letters from two otherwise identical pages of text. |
|
| |
"I v n o | n e t r" = "Inventor", for instance.
|
|
| |
I'm pretty good at stereo viewing, but it didn't work well. |
|
| |
Working in text, the first problem turns out to be that not all letters are the same width, so they can't be replaced with standard spaces. The text doesn't line up unless the gaps are exactly as wide as the missing letters. |
|
| |
Like this a-way, dig?
L ke t is a- ay, di ?
Although that depends on your text viewer. |
|
| |
I then took a screenshot of the text, pasted two images into Paint side-by-side, and cut out every other word from the left image, then did the same in the right image, for the alternate words. I then crossed eyes and looked at that. Man, that hurt! There was no part of the image in common where I was looking, and I couldn't keep the right amount of cross at all. |
|
| |
To make this work, I think, there would need to be identical kerning (character width) to/for the missing letters, and some text in common to both sides, maybe a third of the text. Which would make a single page of the text less incomprehensible. |
|
| |
I'm not experimenting any more. Ow! |
|
| |
I'm working on it, I...oh you meant...never mind. |
|
| |
If I understand correctly, you want to
use stereoscopy to merge two pages
which each contain half the image, yes? |
|
| |
It won't work. Stereoscopy relies on
your eyes being able to find
corresponding parts of the two images;
your brain then does the necessary
superposition, and percieves depth
from the small disparity between the
two images. |
|
| |
If the two images are not similar, your
brain won't merge them - they'll
dissociate as soon as you look away
from the 'dot'. |
|
| |
I disagree. The images displayed in the links do not dissociate as I look away from the dot.
If two combined images produce the letter A for instance, the fact that they form a recognizable shape should keep the eyes focused on the alphabet the brain knows. |
