Slashdot Mirror
The Goggles, They Do Nothing
Suchetha writes "In anticipation of a slow news day i would like to direct the Slashdot hordes to Akiyoshi Kitaoka's Optical Illusions page. The page also has explanations on why/how they occur (in icky PDF format). The page is on a .jp uni server so they SHOULD be able to handle the herd of rhinos that is ./."
Use the cache so more people can see! Thanks!
Caution: This page contains some works of "anomalous motion illusion", which might make sensitive observers dizzy or sick. Should you feel dizzy, you had better leave this page immediately.
Some of the pictures on this website can cause dizziness or might possibly epileptic seizures. The latter happens when the brain can't handle the conflicting information from your two eyes. If you start feeling unwell when using this website, immediately cover one eye with your hand and then leave the page. Do not close your eyes because that can make the attack worse.

It's nearly dead. That is what you get for tempting fate in your fscking summary. ;->
Some of these are on display on out-of-the-way doors in the Exploratorium science museum in San Francisco. It looked like some of the staff members had printed them out and posted them there for their own personal satisfaction, but a lot of the visitors were finding themselves distracted from the bigger attractions to stare at these.
It was trippy to have the spinning snakes one as my wallpaper for some time, but at six by four feet, it really does begin to make you a little dizzy.

if you shake your head you can see the dots moving!
and no headache! w00t!
sure, today is a slow news day, what boring. gee.
Here here
I'm in cafe nursing a severe hangover. That shit almost made me yak all over my laptop.
Because I could...nay..have found myself staring at these for periods, and assummed I will get a bit of headache, of that they are bad for my vision (thus forcing myself to stop).

Yes, your eyes will shortly fall out of their sockets.
Hopefully you're able to read this before that happens.

Some of these images have been copied elsewhere. Google Image Search shows some of the pictures, such as rotsnake2.gif

The laboratory of Dale Purves at the Duke University Medical Center is also researching visual illusions. Check out www.purveslab.net for interactive animations (yes, it's a Flash site).
He's also written a book entitled Why We See What We Do: An Empirical Theory of Vision.
Archive.org to the rescue!

This will probably get slashdotted really quick because the archive.org servers are already slow. Someone make a mirror of this page quick so everyone can have a piece!
I had seen this before and was looking for a custom wallpaper manufacturer to have the Rotating Snakes illusion made into wallpaper for my bathroom. Just for the entertainment of having my friends to to go to the bathroom after a long night of drinking...hilarity ensues.
You need to stare at it for a bit for it to work... a casual glance won't do it. Now maybe if it was on the front of a girl's tshirt...
:) Guy stares... 5 seconds later... epileptic seisure!
Actually that might be a good protection for girls that don't like guys staring at their chests
Just use this. Just saw it on Wired. They mirror every website Slashdot news includes.
We prefer the term "crash" to refer to a gathering of us... herds are so... blaise.
Congregations of other animals have different terms...
A murder of crows
A gaggle of geese
A pounce of cats
An ambush of tigers
More can be found here.
These optical devices could potentially be quite useful... going to have a play :-).
Engineering is the art of compromise.
... should use PNG instead of GIF. First, as we all know, PNG aren't animated, so no-one will be fooled into thinking that maybe these are animated gifs ;-)
But jesting aside; 310097 rotsnake.gif vs 262253 rotsnake.png, 46.7KB saved for that single image, or about ten seconds download time for a modem user.
Belief is the currency of delusion.
A very cool illusion is available here. Try looking inside of the triangle defined by the yellow dots, as the blue dots wander around. After a few moments, the yellow dots begin to blink in and out of your visual consciousness. It's quite a powerful effect.
Check out this image. The squares marked "A" and "B" are the same shade of grey. If you don't believe me, open the page in a paint program and check out the colors.
"that would be a japanese university server. you must be american."
Look! Mozira!! RUN!!!
"Derp de derp."
lol. But sriously, the JPEG artifacts cause the values to be *slightly* off on some pixels. But I encourage you to cut out the A square and drag it next to the B square. When they're next to each other, they look exactly the same.
One of my customers had the computer sitting in the corner, so as you face the computer, you're also facing the corner.
The trouble was, the wallpaper was vertical blue and white stripes, each about 1 inch (2,5 cm) wide, covering both walls.
Sitting at the computer, seeing the striped wallpaper in your peripheral vision, you would get the unnerving feeling the monitor was attacking you, slowly approaching you, menacingly. (It didn't help that the monitor was on an elevated platform, so you actually had to look up at it.)
After a few years, they covered the wallpaper with wood paneling.
Give me my freedom, and I'll take care of my own security, thank you.
That has to be the nicest color illusion I've seen. I believe that the illusion is so good, that the only reason the dropper shows both squares being (170, 170,170) is that even the GIMP was fooled by the shadow.
