I've actually always had this search engine dream. One day you'll be able to see a picture of something or take a picture of something, and load it into a search engine and have it scan the pic, search, and tell you what it is. So you see a flower, stop and take a pic of it, and Google will tell you what kind of flower it is. Or you can take a pic of a fungus growing on your favorite plant and Google will be able to tell you what it is by scanning the characteristics of the pic. Cars, people, buildings -- it should work for whatever you can photograph
