Follow the instructions to mess with your brain

1. If your eyes follow the movement of the rotating pink dot, you will only see one color, pink.





2. Green Catastrophe: If you stare at the black + in the center, the moving dot turns to green.





3. Now concentrate on the black + and soon all the pink dots should disappear.


Follow the instructions to mess with your brain. We"re in your skullz messin" with your brainz and blowin" your mindz.

And if you look at a white screen immediately afterward, you see a ring of green dots.

@MikeyNiv: Because you do 3 "experiments" with them. Then you can go back and re-do the same experiments with the earlier gifs, which now produce different results!
That shows that it`s not a "video trick" but in fact something weird going on with your eyes/brainz. :-)

Just glancing at them I saw green flashes and pink dots.

Following the instructions caused the same described effects on all 3 screens.

I`m guessing it makes "colourblind spots" by the green cancelling out the pink before the eye can recover...

Nice to have you "home" @Angilion! :-) Welcome back!

Gah, the cut-off <1000 characters is still here.

No idea about the colour change, though.

5Cats: I thought it`s probably processing rather than hardware...so I looked it up.

A bit of both, apparently.

[quote">Clarke and Belcher (1962) showed that the saccadic displacement needed for a faded image to recover is too large to suggest a ganglion or preganglion origin of the fading. On the other hand, they failed to find binocular interactions of the luminance threshold for the fading, suggesting a precortical origin of the fading. They concluded, therefore, that Troxler fading most likely arises from the adaptation at LGN, the relay station between the retina and the cortical visual areas.[/quote">

related experiment

Our brains dynamically vary the weighting of sensory input, tuning out unvarying inputs. So the dots are detected by our eyes but ignored by our brains when we`re not looking at them.

No idea
