From the 2sidez web application:

2sidez: What would it be like if photos had 2 sides?

2sidez comprises both this website [note: this website is no longer available] and an application for Android phones that lets you explore 2-sided smart phone photography online and offline.

The 2sidez smart phone app for Android devices lets you capture pictures with front and rear camera simultaneously. It gives you the opportunity to frame memories and moments in an unprecedented way. Frame your pictures simultaneously and share them instantly! The Android application captures what we call 'duographs' (duo + photograph).These are photos that have figuratively two sides - one framed by the front facing camera and the other one by the back camera.

The 2sidez website is where this new kind of photos gets posted. You can find two exemplary duographs below and many more in the recent posts section. We invite you to create your own duographs and share them with your friends on 2sidez.com. You can also share your duographs via Facebook, Twitter or Tumblr.

Please download the Android app and sign up. - It is that simple! 2sidez is also a photography-experiment to find out what it would be like if photos had two sides - your photos will help us understand this!

2displayz - An Image Viewer Prototype for Duographies

Currently I am investigating different ways and devices for looking at duographs. The prototype shown in the video below aims at providing a more tangible user experience when revisiting old duos.
