Layar, the augmented reality browser which lets you search Google Local for locations in your area and then overlay them on an image captured by your camera, has now been made available for the iPhone 3GS.

Long a favourite of Android users, the app displays information based on the direction you're facing. You can spin around in circles to view different results until you're dizzy and fall over. Notably, it's based on an open architecture so it can grab information off any service that wants to talk to it.

In a test search for "pubs" we found it accurately displayed all the local pubs in the area, and even some that had closed down. You're not limited to Google local, either - you can also view Wikipedia info, local Twitter users, public transport points, Flickr photos, property for sale or restaurant recommendations.

Layar is a free download for the iPhone 3GS and Android.
