I found this optical illusion through my Google Alerts email, and noticed it’s pretty interesting. At first you may miss the illusion, but if you watch carefully the center of the brown “dot”, you will notice that it appears to be expanding. The effect by its nature, is quite opposite from other illusion located in disappearing effect section (which I updated just now), but it works in the same way. Just think of it like this – the center blurred spot isn’t vanishing, rather expanding, but the outer yellow surrounding is slowly shrinking (disappearing). This is the reason why I placed it in the same category. You may want to check stronger examples like vanishing haze, but you should also visit expanding cushion and expanding block that aren’t much similar, yet they also seem to expand.
