Looking for some random photo exchanges (not that kind) the kind that involve mystery, anonymity and a circular frame? Check out the free and artsy photo sharing app called Rando. “..an experimental photo exchange platform for people who like photography. A rando is an image that is taken by you and sent anonymously to somebody completely random.” You have to send an image to get an image. You’ll never know who receives the photo you are sending, just a general approximation of where that person is located. The app is free for iOS, Android and Windows phones.
