Nokia's new beta of City Lens is fantastic. It's an augmented reality app that is really neat and i think everyone who owns a Lumia 800 or 900 should try it out!

I grabbed the below article off Nokia's website and gave the app a shot, i love it.

Good thing to note is that it is still in beta so you'll still find some bugs for sure.

But try it out!
