The Devils fork is a visual optical illusion, it is a simple angle trick. The way we see things is usually increased by what we are familiar with. For example when we look at an object we see only one angle of it, but in our brain is making up the whole picture. It is a picture of a 3D image but we know its only a 2D object.
