This is similar to an optician's test for blind spot.
they got this 1 all over the walls at my school it's scary
This is a fun one
Even through it's popularity it still is baffling
Try telling your little brother/sister to touch the dots with their fingers!
They'll keep looking at their fingers!

Also because they look at their fingers the dots dissapear.

Soooo cool, where did you get these from?
Yeah and if you stare at the black squares, they grow in size!!
I wonder if it's because your eyes mix the black and white together to get gray. Hmmm....

LOL i saw it b4....its a classic
I think that you should hide your answers so they can work it out themselves! like in the logic grids n mysters!
Yes, it's a very interesting illustion, but I feel that the Scintillating Grid Illusion is a more effective version of this one.
i pretty much say the same thing as 'mr.tickles'. Anyone know how this works? i myself liked the idea of the eye mixing black and white.
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.
