Awesome! I saw the spider, and now my eyes hurt. x-x

Oh.

Awesome!!! It's so nice !! I saw the spider !! I love this optical illusion ! :) ;)

This is one of the best illusions on the site. It seems to vibrate randomly when you stare at it, and then stretch. When u stare at it for 15 seconds and then look at a wall and blink rapidly, you can see something that looks like a flower. pretty cool

that spider is awesome, how does that work? anyone know?

AHHHHH! I'm scared of spiders!! Well, cool illusion though.;)

Yeah it 's once again awesome!
First it did'nt work for me either
...

---> you have to move it up and down very quick. It's not necessary to move it al the way up and back all the way down. Just garb the side-bar (with left mouse button) and move it a little bit up and donw. Just let the picture vibrate...

>> how does that work? anyone know?

Your brain doesn't like moving complex shapes. If he doesn't want to have a headache, he has to simplify the shape (with a maximum of horizontal and vertical line). You see a spider, but it's just a coincidence (oblic lines were "rounded" to a horizontal or vertical direction).

stare at the centre of the spiral for about 30 seconds then look at you're hand. pretty cool i think!

That is creepy!! Very cool illusion!

I've got a mission for you. Count all the lines without help from mouse =]

Wow! That's amazing! I also noticed that when you look at the center for a prolonged period of time, it seems that the edges are bulging in and out.

Keep up the good work Vurdlak,

I see a comic book style action star shape... like the cheesey 'Bang!' thingies.

saw the spider too, and the halucination

This is cool. I got the spider thing. And the flower thing. But now I am very confused...

my eyes hurt now but i was a sun flower some how

Just gave me sore eyes.

Wow it really messes up your vision

very nice illusion!

On my google widget, the illusion wont come up. It just says "Invalid data", but if i click on it it comes to the site. I dont know what wrong with it!

if you stare at it for a while and close your eyes you can see something that kinda looks like the sun

really kl! yh i saw the spider 2. does hurt ur head thou...

I used to make op-art paintings like this illusion. My favorite was where I hid the names of song titles in a particularly psychedelic design. I might have some of these paintings in storage.

Thats really amazing I've seen something similar by Akiyoshi Kitaoka, can anyone see colours or is it just me, maybe it is somthing to with the monitor because I doubt it would happen on paper

"Keep up the good work Vurdlak"
I'm the one that made it >:(

"Count all the lines without help from mouse =]"

i saw a spider too

This is jsut you seeing waves like magneitc waves, this makes it look like it is a spider or a flower etc.

stare at the center then shut 1 eye

when i blink rapidly my vision turns green for a moment



now it hurts to move my eyes


X_X

wow I still see a low transparency of this image over everything I look at 5 minutes after looking at it.

i think u can c it scrolling up and down

I tried opening the image. Bad idea. I almost had seizure and when I clicked "back" the screen looked distorted.

dizzy and i saw the spider to.

aaaaaah spider! :D great illusion, it does so many things! it has a hidden spider, it ripples when u look at it and if u stare at it for a few seconds and then the writing above it, the writing seems to fold in at the centre!

IS the spider simply an artifact from the digitilisation of the curves. I don't think you would necessarily get it from a print?
