Google Goggles is a amazing app developed by Google where you can search and find anything on the internet just with a photo. You can take a picture of anything such as art to find who's the artist, a place to find the name, and even a person. I wish I knew about this app sooner in my personal experience and can be used to check the background of a person, place, or thing.  Google automatically scans information of your inquiry on the internet. The app is still evolving.
