Wow! Just done that. The bloody yellow spot just walked out in front of me! No I've not been drinking.

Hic.

The test is bollocks, an optical illusion that exploits the fact that "blue" and "yellow" are "opposites in the colour spectrum. The same happens with "Black" and "White", "Green" and "Red". Hth.

No it doesn't. It exploits the fact that the moving background tricks your brain into ignoring the static dots. If you blink or look away then back the yellow dots will reappear. It should work whatever colour the dots and grid are.

this is my favourite one


how did i miss that?

Here's two perfectly round concentric circles. Your brain won't let you see them that way, though:

If they cross the road when I am on my bike I will go straight over them both. My apologies in advance to Mr, Mrs and baby circle.

If what you're seeing through your wind-screen is rotating 360 degrees every second or so you're already in trouble.

Christ! I've never seen them when commuting on my motorbike. I'd better get me eyes tested.....

Don't look at it too long, it makes me go all

More importantly pushbikes!

The dents from a pushbike are nowhere near as bad.

That test I think shows why you miss motorbikes. You look at the flow of traffic and I suspect if the bike is not in your line of vision you might not see it at all.

Afterimages
When one stares at a single color (red for example) for a sustained period of time (roughly thirty seconds to a minute), then looks at a white surface, an afterimage of the complementary color (in this case cyan) will appear. This is one of several aftereffects studied in the psychology of visual perception which are generally ascribed to fatigue in specific parts of the visual system.[1]
In the case above the photoreceptors for red light in the retina are fatigued, lessening their ability to send the information to the brain. When white light is viewed, the red portions of light incident upon the eye are not transmitted as efficiently as the other wavelengths (or colors), and the result is the illusion of viewing the complementary color since the image is now biased by loss of the color, in this case red. As the receptors are given time to rest, the illusion vanishes. In the case of looking at white light, red light is still incident upon the eye (as well as blue and green), however since the receptors for other light colors are also being fatigued, the eye will reach an equilibrium.

If the yellow dot was a small child you'd be fine. It's when the green dot is a small child that you have a problem.

Outside Camberwell Bus Depot yesterday I saw a motorbike run into a pedestrian about 50 feet in front of me. Pedestrian crossing the road and was roughly in the middle. Absolutely no traffic within 10 feet. I suspect he is going to be worse off than her as he swerved about a second before and glanced her.

Maybe all motor vehicles should have a man with a red flag in front of them?

I did that, spilt me Tennents Super all down me leg...

Interesting test here

Now imagine that yellow dot was a small child ..
