I installed what appears to a cool app the other day called Reality Browser 3.0. I still don't fully understand its purpose except it uses my camera. When I wave the phone around it will display pictures of people. For example it works in conjunction with other things like Twitter. It can show you the exact address someone tweeted something....that can be cool and yet crazy at the same time! Has anyone used or tried this app? I am still trying to figure out what the main use for the app is but it seemed cool so I downloaded it! LOL!
