To demonstrate the power of the brain, here are some cool images that can be perceived in a manner that is different to fact. In other words what you visually see is different to the physical dimensions of the image. Over time, we learn to process some images automatically. As we grow, our minds naturally start to recognise images and associate them with specific meaning. As a result, we interpret images at the subconscious level rarely giving thought to exactly what it is we are seeing.
