Looking Glass is a concept that is still in production, it is a piece of glass that when you look through can tell you what you are looking at and give you information about that, or if you are looking at text, will allow you to do loads of things with it, such as translate it to another language, or do a dictionary search on words that you don’t know. This isn’t out yet but I wanted to include it as it looks amazing!
