With so many of the changes in technology there are some things that will never change. One of these to me has to be exit signs. They look no different today then I remember them as a child. I am sure this is because people know what they look like and that helps if people ever need to find them in case of an emergency. I just find it funny though how some things will never change and this is one that no matter how much changes it will not change much at all.
