You just need to look at the "十” symbol, When you look at it with all your concentration on it for a while. After you will discover all the pink circles are slowly disappearing, and then there is only a green circle going round and round continually... *But then, when you look at the whole pic in detail, all the circle didn't really disappear at all. I think this is a pretty good illusion image! -rolleyes ' ' ' ' ' ' ' ' ' ' ' ' ' -worship
awesome! But it's not magic! (LOL i'm just kidding) I wonder how that works, should try to break the moving gif up and look at each frame of the image...
