I’ve never really been able to get behind the whole augmented reality thing. I tried it with the Yelp iPhone app once while I was on vacation in a large city, but it hasn’t really changed my life in any way. If there’s any platform I can see augmented reality really taking off, it’s on smartphones.
The developers at Crossfader have released something really cool: an augmented reality layer for Maps on the iPhone. Both Apple and Google Maps are supported, and the app itself is totally free.
