Someone has come up with the idea to create a thing that is about the size of a cell phone and you pull out a screen which uses image recognition to match whatever your looking at to a database of google images or something and then tell you what it is. Also has GPS technology. Now the cool thing about this is that it is a stupid idea and no one is ever gonna need to use this. I also like how they use Google in their images even though it is not a Google product.
