Our first optical illusion
It seems like the dots move from the actual intersection that I look at. Pretty cool!
Awsome! Thanks for bring this category in, i love these!
These are great!!! Keep bringing them
I love optical illusions thanx for introducing this section and braingle's new design is cool.
This praticular optical illusion has been known to cause seizures. As you dart you rvision from each dot, it flashes, causing many flashes in an attempt to catch the dot you're trying to find. Since I'm Epileptic, could this be removed? Or at least have a warning on it?
I agree.
I love optical illusions - Thanks for these Jake they are great
Yes it is a wonderful addition to this site
Yes i love these things!!!! But i agree with hated also.
I found this one hilarious when it showed up in my inbox one day posed as a joke on the ballots in Florida during the whole Bush demanding a recount fiasco back in the day.
Whoa! how do they do that?
AND?
I like this one i wanted to submit it i guess you beat me to it. hee hee hee

Man, I hate having spotted vision, freaks me out. Cool that you could create thta sensation this way though .
How the heck does that work??? Although I thought it was cool it made me feel like throwing up
That's so cool!!! It's amazing! I LOVED IT!!
thats coool
Cool, but several optical illusions do cause seizures (spinning and flashing ones) - perhaps a warning to the epileptics is needed? (not necessarily removed... a child old enough to participate on braingle should be aware of their own tendency to seizures)
very cool! my fav
This goes on the same principle as staring at a jet flying across the sky. When there is a white trail behind a jet, some times your mind will want to create a line in front of the jet to form a whole line accross the sky. Don't think so? Try it out next time you see a jet!!
This is me after looking at that.

THE DOTS OF DOOM!!!
Hey, if u cross you'r ieys, a circle will apear in the midle of the pictur.
I'm no opthamologist so feel free to correct me if I'm wrong, but I think it's similar to the US Flag illusion. If you stare at a color for too long, the cones in your retina or the nerves from them get 'tired' of sending that color; they run out of chemicals or neurotransmitters or whatever. When you then look at white, the complementary colors wake up rested and refreshed and transmit their part of the white light (which contains the entire visible spectrum). So, your brain sees the blue part of the white light but those poor orange (red and green?) cones are still too tired to transmit. So your brain only senses the blue behind the stars.
In this illusion, the white fatigues all of your cones so the complement is black. This illusion is designed so that as you move one intersection left, for instance, the intersection you left mostly fills in where the one on the right used to be, increasing its saturation time.
It seems, too, that the fact that you have many fewer cones outside your focal point makes it easier to fatigue the ones farther from where you're looking; maybe there's some load sharing among the cones in the focal point to keep the problem to a minimum where you're looking.
You will notice, if you can keep your gaze perfectly still on one intersection, nothing moves. But when you finally do move, the effect is stronger.

one of my favourites
one of my favourites

Very cool!!!!
Sweet.
cool
wow.. why it happens like that? Sumbody kno?
::YAWN:: thats been outdated!!!
Whoa...making me dizzy...nice one!
I like this one, even though i see these ofton there always cool
Hey you can only see the black spots when you don't look at them...Eh?
pretty cool, i guess
for the first one on the website it is ok
BRAINJUICE THE ANSWER TO UR Q IS YOUR BRAIN CAN NOT TAKE TO TO MANY LIGHT COLOURS AND DARK COLOURS AT THE SAME TIME SO YOUR BRAIN NEEDS TO TRANSMIT DARK COLOURS IN LIGHT COLOURS. DOSE THAT ANSWER YOURE Q? IF NOT PRIVET MESSAGE . GOOD ONE!!!
WOAH!! I THINK I NEED A TYLENOL OR SOMETHING! KOOL!!!
its OK not the best though!
That is cool but I have seen that many times before.
This one was my favorite! You saved the best for last!
kewl.
My fave, too!
Try crossing your eyes - I found I could see two squares and they were blue and yellow. But the actual effect was really cool.
SWEEEEEEEEEEEEEEEEEEEET!!!!!! I love that!!!
itd be funny if that was programmed to do that.
fun though
fun though
I've seen stuff like this before, but I always enjoy it when I can't figure it out. Why is this happening????
WIERD AND COOL AND FREAKY!
I am sure there is some logical explanation for it, its just that no one knows it.

Lol u did one more like dis 2.But I have this in my book 2. but its still kool. ;)
Scintillating! Thank you!
omg THAT WAS SOOOOOOOOOOOOOOOOOOOOOOO..... k~ORAL
Man, I just love optical illusions. I don't know how this one works, but it does.. Now I have to close my eyes for 5 minutes or I'll get dizzy.
This is another "classic" optical illusion-but it's classic for a reason.
great work
great
choose a spot ( a corner white dot thingy works best) and stare at it for 30 sec. then look at something white or close your eyes. its okay to blink. if you have trouble looking at one spot for very long, imagine disecting molecule after molecule of the white dot and that should help. i love this one!
it makes my brain hurt!
OMG!!! How does he do that?! Its like it just does it!!!
that was so cool i luv these tytpe of things!
Like some are asking, how does that work? I thought it was very cool... yet freaky! LOL.
Cool. This hurts my eyes just looking at it.
Superb nice!
I liked it,it seems like black spots were flashing alltogether at the intersection.
My eyes were going woowooo from all the flashing.

classic illusion. just love em'
great magic
$ourDough liked this one!
$D
$D
one of my favs - this one is great
Endlessly playful.
When my eyes lose focus, some of the grey gridlines drop out, creating new, larger black spaces; or many of the dots (white or black) disappear, creating new constellations,
With my eyes crossed, the whole thing goes 3D, really!
Also challenging (but less fun) is holding your gaze on one intersection long enough to keep the black phantoms from flashing -- ever.

Reminds me of the old days. Groooovy!
I only see it when I close and open my eyes.
That one was cool.

I SWEARE MAN THIS IS THE BESTTTTTTTTTTTTT ILLUSION I HAV EVER SEEN. THAT IS TIGHTTTTTTTTTTTTTTTT
I love Jake's quizzes! They are all challenging, yet fun. Another one I recommend is Man Or Woman. It's challenging.
It hurts my eyes.
I think that it was pretty cool, but some how a little bit of a waste of time though.
Anyway it was really good Jake.
Could anyone explain how that works?

This is amazing how they do this!
I just looked at the gray circles for like 15 mins, and then moved my eye 1 millimeter, and then I saw it. When I closed my eyes, I saw a chicken. I did it again, and I saw well, a chicken.
bookworm1 u dont need to be so inappropriate. Some of you post thing that should not be on here including: 1)"Old people have half a brain as 20s-30s people." (Insulting people)!!! 2)"YOU ARE A LOSER" (I don't think this kind of stuff should be posted) 3) "CUT THE BULL**** (being vulgar and mean), so I think whoever does this, if you got to much bad karma,and/or deleting user, u deserve it...
If you spent time reading my comment, thks and I hope 🤞 you learnt something from that. Luckily, this is in 2005-2010, so yeah... Thanks a lot, and good luck all of you! â¤ï¸â¤ï¸â¤ï¸ðŸ˜„😄😄
I just wanna say no one has been using braingle for a VERY long time. so many people's comments are offensive and I don't want braingle to be a place where cyber bullying happens and people get offended. Braingle is a riddle website, not a place to offend people. If people spent time reading this thanks a lot. Good luck to all of you
boring
This is pretty cool! Can I ask how it works
Thats cool
Enjoyed it. Very amazing.
