Today’s optical illusion video rivals the original Checker-Shadow Illusion, one we’ve originally seen created by MIT professor Edward Adelson, way back in 1995. This illusion was later recreated number of times, and by time, all of them variations demanded their very own category to be listed under. The version we show today was recreated by R. Beau Lotto, whose motive was used by creator of this video to show the effect in action. As Neatorama reports, this illusion shows us how the human visual system is not that great at being a physical light meter.
Since I’ve introduced you to our very own hosted video player, I just can’t get enough of posting all those clips. I really adore the simplicity of our player, but the only problem I couldn’t overpass is the “defer” java script attribute appended to the plugin. Why is this such a problem? Since you all know me as a perfectionist I am, I can’t overlook the fact how the video is the last thing that loads on the site (due to the defer attribute). I tried removing it, but no luck! Can someone out there come with the quick fix, that lets our player load immediately? I would be more than grateful! Fixed! Does it work properly (player shows immediately) now? ;) Btw, you can see more of greeenpro2009’s optical illusions if you check out his YouTube channel.
I had to watch that video a few times!
It always astonishes me the way our eyes can play tricks on us like this. Thanx for keeping us aware of our own inability to distinguish truth from perception.
haha first comment but you can already see those tickets at the start and also they have there in the shadow the same color as at in the light on top
Look at the wooden background, the wood is a different colour along the horizontal line that he moves the pieces of paper across
That was quite shocking. I watched it a few times and was surprised at how the human mind decides what a color or shade actually is.
Sorry Vurdlak, I’m not that computer literate to help with a quick fix. What I think I saw was a hand manipulating two pieces of material to the ends of the “table”. there was some editing involved,I believe.
Wow, had to copy the image to Paint and cut and paste pieces of it myself to believe it…
The bottom grey bits are really the same colour as the top…
I actually tried the experiment of cut/paste to prove it wrong, haha! You should have seen my eyes pop out when the pieces actually “melted” into each other.
wtf how is that done??
that was pretty freaking awesome!!
sorry i don’t know anything about the technical stuff.
For me , the “relative shades of gray” illusions are some of the strongests and most difficult to understand. I know it is related to saturation of the electrical stimulation in the cones of the eye. But the effect is so strong it always seems like some sort of magic.
this one is particularly neat because of the apparetnt and immediate shade change.
i’ve seen something like that already but still prety good
Wow. I know it’s flat but I just can’t make myself see it. Great illusion.
I see it but I still don’t belive it
please change your video player. THIS ONE SUCKS!
omg i always knew tht u were lying when u said they were the same color but i just couldn’t understand it. now i do just cuz of this awesum vid. love this site come here everyday 4 a new illusion.
p.s. yes it did work immediately 4 me. it was the last thing but didnt take more than 5 seconds. mayb cuz im using a macbook.
Nice. If you take a screenshot of the box, put it in a picture editing program, and then move the section your self you can easily see how the ‘colours’ change when you move the section around the screen.
You could try moving the script into the head section of the document and then wrap it with a jquery document.ready call.
WooooooW, nice
*gives Hoffman a thumbs up*
*gives anon a “be useful” talk*
great illusion, if a bit old… but what illusion isn’t based off old ones? :)
If it were really an illusion, why does the loose tab have to be rotated? To me it looks as if the tab could have a reflective surface that changes depending on which side you’re looking from.
This is the best one yet. Some are a little easier to anticipate but this one blew me away.
I seriously think the investigation you realize deserves more than be prized. Your work enhance any effort we at teachers do at academies.
Congratulations!

Sorry same congra
Our brain is indeed a good light meter… but is definetely and better yet a integrative system, that learns from experience and considers not only the physical aspect, but also the most probable scene reality, given the surroundings. It’s the same situation with the checkerboard (A and B square comparation) illusion.
This was easy I could see the pieces steight away!!!
THAT…WAS…REALLY…COOL!!!!!!!! the first time i was like WOW! and now im like OHHHHH!!!
I ran the clip several times. Still amazed.
its all about shadows. they were always grey, they never changed. its just that when we saw them in the light, we realized they were grey.
Had to print screen and cut and paste bits of it to check it was real! Took me ages to believe it!
Actually, they are clearly different shades of grey – I froze the video at the start, and used Colorpic to measure the shades – the bottom grey is around #353535, the top is around #656565.
So unfortunately this video is an epic fail. They are NOT the same shade of grey.
Do it yourself with Colorpic.
h-h-how come???
what is that he is moving it is not paper can i be bold enough to venture glass? please correct me if i am wrong and has he simply painted the box on the floor ?
hmmm…i dnt believe this not because i cant understand the intricate and delicateness of it but simply because i believe you all seem to over estimate it :O ohhhhhh ahhhhh :D
