Layar has developed an Augmented Reality program that currently runs on Android on the G1. Sure it only works in the Netherlands right now, but there will be other layers soon. What makes it great is is constant connection to the internet and its ability to tell you whats around you.

I remember reading articles on AR systems that required the users to carry around large backpacks with a huge antenna sticking out of it. They also had to wear large helmet visors just to be able to see simple things like way points. Now they have these systems built into phones that require no external attachments.

Imagine being able to pull up points of interest when traveling and be able to find them by the floating arrows above them. Never get lost in a city. Best of all, play games in the real world making it way cooler than the Wii. There are all kinds of different uses that are yet to be dreamed up. This is the stuff of sci-fi!
