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