ZipRealty offers 'augmented reality'

Pointing iPhone camera at homes reveals whether they're for sale

ZipRealty has added augmented reality capabilities to its iPhone application, allowing users to determine whether a home is for sale — or has recently sold — simply by pointing their phone’s camera at it.

As users point their phone’s camera in different directions, the "HomeScan" feature of ZipRealty’s iPhone app displays the address and distance to any properties that are for sale or have recently sold as they come into view.
