Surprising what the human eye and brain interaction can do.

Brilliant. but where is the full colour information encoded in the picture? Could TV be revolutionised by this method, look at the red dot and the black and white show erupts into colour.

Edit if you stare at the green dot you'll see Tidal Pete all night.

It's just the original image with the colours inverted, Bribie. Like a negative, essentially.

Yep... starting at the image depletes the photo-receptors in the eye. Where the image is red, the red receptors will be depleted, where its blue the blue will be depleted and so on. So when you stare at a blank surface the receptors that aren't depleted fire at full strength and the depleted ones don't and you are left with an inverted after image until the receptors recover.

Biology is amazing.
