After you've done your recon and feel comfortable with your surroundings, it's time to get busy. Much like Wikitude, Layar will project points of interest on your screen using GPS to determine your location. However, Layar has MUCH more diversity. Layar has a ton of categories ("layers") to choose from including places to eat, drink and apartments to rent. If you're a Twitter user, you can even locate other tweeps using the service and that is just scratching the surface of the available layers.
