A Personal buildAR account lets you create your own Points of Interest (POIs) using a simple map based interface. You can set each POI to be private or you can share them with everyone by making them public. Personal accounts are normally US$4.95/mth but sign-up now and you'll get the first 3 months FREE. You can also set up Points of Interest and view POIs on your mobile phone using the Layar application for Android. It will also soon be available for the iPhone too.
