Nothing will be left undocumented in this Age of Apps—a new one even aims to tell you who rode in your cab before you got in. Think of Taxi Snapshot as being the transportation spin on your typical geotagging, mixed in with a little photo booth action. It can get so lonely on that open road, but now you don't have to worry about spending that time without a screen in front of your face or without a new way to connect with others! This really fills the void where Facebook and Twitter and Instagram and Foursquare don't, ya know?

Photos are grouped by the cab's medallion number, so at least you'll have that handy if you should leave something behind. [via Petapixel]
