This is a lovely and somewhat strange illusion. Stare at the red dot in the left-hand image for about 20 seconds, and then look at the centre of the right-hand image. All being well, lots of strange stuff will happen in your brain…..
Did it work for you? What did you see? People seem to see different things.

Is the 3D effect what I’m looking for?
April 27, 2011 at 9:02 am
a 3Dish net like thing.
maybe i wasn’t focusing as much cause partially i’m trying to count to 20. (i’m a bad multi tasker)
April 27, 2011 at 5:40 am |
For me, the right image went completely grey when I looked at it… though maybe I wasn’t looking right at the center.
April 27, 2011 at 5:42 am
Same here. Also, while staring at the red dot I became VERY aware of my eyes’ natural saccade, because every minute perturbation showed up quite immensely.
April 27, 2011 at 5:42 am
Tried it again, and this time it seems to look like a checkerboard pattern (if a bit greyed out).
April 27, 2011 at 6:21 am
It’s supposed to be grayed out. Your eyes suffer retinal fatigue looking at the white zones (contrasted by the blurred black) and show the negative of the image (white turns to black; black causes little fatigue), so when you move over to the next image, the “fatigued pattern” fits over the white, creating a solid image in your brain, even as a patterned image sits in front of you.
At least, I *think* that’s right. lol
May 9, 2011 at 7:21 am
Yep, all grey here too
April 27, 2011 at 5:57 am |
Yes
April 27, 2011 at 6:41 am |
I saw ripples on the right image. Is that it?
April 27, 2011 at 7:23 am
Ripples. Same here.
April 27, 2011 at 6:44 am |
Nope! Looked the same to me.
April 27, 2011 at 6:46 am |
For me the right-hand image repeatedly popped into and out of focus.
April 27, 2011 at 7:16 am |
Briefly the right hand image became a chequered pattern.
April 27, 2011 at 7:16 am |
For about fifteen seconds, I saw a thick line going from top-right to bottom-left turn all blurry and flicker a lot. It was quite freaky.
April 27, 2011 at 9:54 am
pretty much got the same
April 27, 2011 at 7:54 pm
Same here, I think!
May 17, 2011 at 10:43 pm
that happened to me too =)
April 27, 2011 at 7:19 am |
The right hand image started rippling in the centre of the image.
April 27, 2011 at 7:20 am |
Definitely flickering and twitchy
April 27, 2011 at 7:21 am |
For me, the right image went flickered a bit before going completely grey, but I also got a faded image to the right of that, presumably from having had an image just to the right of the one I was originally staring at.
April 27, 2011 at 7:41 am |
I also saw it turning flat grey and rippling effects after that. I did not see a checkered pattern or flickering. It is pretty freaky, that’s for sure.
April 27, 2011 at 7:55 am |
I could see the dot from the left image flashing in my peripheral vision.
April 27, 2011 at 8:15 am |
Flat grey for me, although it did alter slightly at points.
April 27, 2011 at 8:50 am |
Looked like a pulsating brain from a b-grade horror flick.
April 27, 2011 at 8:53 am |
The diagonal from top right to bottom left oscillated from side to side – quite a persistent effect too.
April 27, 2011 at 4:04 pm
I had a similar experience. The left image moved smoothly to the left one time then oscillated side to side.
April 27, 2011 at 9:52 am |
My eyes got really itchy and started watering. Neat subliminal advertising for eye drops.
April 27, 2011 at 9:59 am |
so that’s where fog comes from
April 27, 2011 at 10:55 am |
Yeah, it works. Basically, parts of the image fade in and out. Sometimes it’s only the lines in a “/” direction that fade, sometimes it’s only the lines in a “\” direction that fade, sometimes it’s only a particular section of the image that fades, and sometimes it’s the whole image.
April 27, 2011 at 11:45 am |
I’m seeing all kinds of weirdness. Checkerboard pattern; rippling movement; grey patches; general fuzziness.
April 27, 2011 at 12:14 pm |
Effect 1: almost disappeared entirely. Superseded by Effect 2: checkerboard only at the bottom right hand corner up to the middle and blank at the top left to middle, superseded by Effect 3: rugby ball shape with a cross in the middle. Then finally flickery and twitch and general fuzziness back to the general fuzzy original.
April 27, 2011 at 12:37 pm |
I see a cross…
April 27, 2011 at 1:24 pm |
I saw just the image as it was before I started doing all of the staring…
April 27, 2011 at 1:25 pm |
i saw a checkerboard effect
April 27, 2011 at 2:16 pm |
Some of the lines disappeared and others became more prominent so the star shape disappeared – kind of looked like half of a three-dimensional ball for a while at one point.
April 27, 2011 at 3:35 pm |
good variation on the theme of retinal retention – using one image to cancel out the other – and waves , not unlike the original title sequence to Dr Who (1963 version) appear to result.
April 27, 2011 at 4:13 pm |
The image on the right looked a bit 3Dish
April 27, 2011 at 4:19 pm |
The right image moved a lot and looked distorted.
Great illusion, probably the best I’ve seen here.
April 27, 2011 at 5:42 pm |
Thats nice, it turned 3D for me!
April 27, 2011 at 6:33 pm |
Weird effect, it blurred and became more clear, blurred again etc.
the effect stops when i stopped moving my eyes.
April 27, 2011 at 7:52 pm |
The line going down from left to right seemed to move back and forth. Did other people see that?!
April 27, 2011 at 8:03 pm |
I saw a ball with a kind of pattern, like a golf ball, for a couple of seconds.
April 27, 2011 at 8:04 pm |
Nothing happened.
April 27, 2011 at 9:23 pm |
Yes. The right-hand pattern appears to vibrate.
April 27, 2011 at 11:06 pm |
Very cool.

Checkerboard.

It just went sort of solid grey for me. No special effects.

If you practice, you can make the picture on the right warp without looking at the dot…
May 15, 2011 at 1:57 am |
Hmm, I saw a quite clear 3D ball in the center, then it started alternating between the cross stripes thing and nearly blank grey.
