What is ' seeing '
A question not readily resolved , as it continues to be the
subject of much research in psycology and neurology.
This site explores the range of what are called optical illusions
http://www.michaelbach.de/ot
This first one demonstrates a motion not immediately apparent that actually
describes how pistons in a radial engine move.
http://www.michaelbach.de/ot/mot_motionBinding/index.html
- Click on the image to view , then there click - occluders

This next one is from another referenced site and shows how the context
greatly influences what motion we ' see '

Back to the previous site , this shows what is commonly called camoflage.
http://www.michaelbach.de/ot/cog_hiddenBird/index.html
- Click on the image to view , then there use - ' Noise off ' and ' Bird stop '

This one is just for fun. Additionally below is attached a zip file containing
these *.swf files and others , along with some common everyday items ![:D](./images/smilies/biggrin.gif)

Great, I've got those downloaded. All I need now is to invite a few friends over, put together some kind of hallucinogen in my lab, and we're off...
Joking aside, these are very interesting. There is a government ad on at the moment talking about how drivers see motorcylists as further away because
they are smaller, resulting in many fatalities.

Seeing is only the result of your brain deciphering what goes into the eyes.
“If Edison had a needle to find in a haystack, he would proceed at once with the diligence of the bee to examine straw after straw until he found
the object of his search.
I was a sorry witness of such doings, knowing that a little theory and calculation would have saved him ninety per cent of his labor.”

Can you ' Captcha ' this ?
I cdnuolt blveiee that I cluod aulaclty uesdnatnrd what I was rdanieg. To the
phaonmneal pweor of the hmuan mnid, aoccdrnig to rceaserh at Cmabirgde
Uinervtisy, it dseno't mtaetr in what oerdr the ltteres in a word are, the olny
iproamtnt tihng is taht the frsit and last ltteer be in the rghit pclae. The rset
can be a taotl mses and you can sltil raed it whotuit a pboerlm. Tihs is
bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the word
as a wlohe. Azanmig huh? Yaeh and I awlyas tghuhot slpeling was ipmorantt!
- Spell checked :
I couldnt believe that I could actually understand what I was reading. To the
phenomenal power of the human mind, according to research at Cambridge
University, it doesn't matter in what order the letters in a word are, the only
important thing is that the first and last letter be in the right place. the rest
can be a total mess and you can still read it without a problem. This is
because the human mind does not read every letter by itself, but the word
as a whole. Amazing huh? Yeah and I always thought spelling was important!

This is particularly useful when responding to those baffling posts which no doubt
have been generated by this very process. Simply excerpt related text from an authoritative source,
http://scienceworld.wolfram.com/physics
http://mathworld.wolfram.com
run it through the balderdash generator and post that as an answer to the self
important gibberish.
Balderdash : Rapid incessant unimportant blather on meaninglessness irrelevant matters.
Gibberish : A term for talking that sounds like speech, but carries no actual meaning.

Something slightly different---I had an amplifier with two red leds spaced ~12in apart and when an object was placed in front in such a way that I saw
only one led with each eye the red image image appeared to float in midair between me and the amp.
The effect, simple though it was, was surprising!
I was seeing the left led with my right eye and vice-versa.
Had I been seeing them the other way round the image would have receded so that it would appear to be at some point *inside* or beyond the amp.

Now, was that hissingnoise or a markov-chain?

That was sequitur. It was about you and markov-chains

Interesting post, the spiral illusion is pretty neat.
I stared at it for approximately 30 sec. and everything in the room around me started expanding.

There's much more to "seeing" than just that. Your visual field is separated into areas of differing visual acuity. If you look straight ahead, you
can read what is in front of you. On the periphery of your visual field, the majority of the information that enters your brain characterises changes
in luminosity, which is not necessarily an image reconstruction at all. Most of the action takes place in your brain. As optical illusions show us,
our brain takes the images from our eyes and overlays them with past memories and experiences to give sense or meaning to the image. Illusions
represent conflicting interpretations of the same image.
A short note on psychedelics, psychedelics will generally suppress the areas of the brain that give meaning to the information that enters via our
sensory pathways. This is why people experience synesthesia and sensory "hallucinations". I put hallucinations in quotes because your eyes don't
actually "see" any of the wacky fractals, it's your brain that is no longer able to fully anchor sensory information to a previously established
physical reality.

Francis Crick describes visual awareness and much more in his book, "Astonishing Hypothesis", which goes into great detail about human vision and
awareness. I will warn that while he states that it is written for the layperson, I found it rather complex and overly detailed with anatomical
neurology, and I have even taken courses in that area. But if you want a non-concise summery of how vision works, it is an excellent book. He has
a number of optical illusions and exorcises to demonstrate certain ways that the brain works.
