How very strange this is.

Follow the instructions on screen, remember to not move your eyes away from the center point.

Very good, was surprised by how much it looked like genuine colour after 30 seconds.

It's weird.

I think in some older thread people came to the conclusion that it has different layers, like one colored, one black and white and one with the weird colors.

It doesn't heh, it's got the weird coloured one and one grey one, you can see that if you dont actually stare at it and just put your mouse over it, even after a period of 30 seconds and over.

It's just two images.

Nope, we figured out something about negative colours making it, so that the eyes saw the opposit colours, when it went back to black and white

Basically, by staring at the funny coloured one for a while you convert all photopigments specific to the colours you are seeing to their alternative form. You need time to convert them back to their original form so they can absorb photons again and signal light. Since you can no longer interpret certain colours in an image, seeing a black and white photo is interpreted not as black and white (since white light is made up of all coloours) but the combination of colours you can detect (white minus the colour of the odd image you look at) so the photo appears coloured. The odd image is designed so that you end up with the correct colours of a real colour photo. Its an optical illuision based on a knowledge of how the human eye detects colour
