One of the coolest features of the HTC One M8 is Ufocus and the 3D effect that can be added to pictures thanks to a secondary camera that grabs depth information. However you don't need a second camera to get a 3D effect on your images. A new app called Phogy allows you to take shots in a way that makes the photos appear to be 3D. The app is free and easy to use. Simply point the camera at your subject and and move it latterly from left to right. Once the image is processed you can rock the device by rotating your wrist right and left to see the 3D effect. This is borderline gimmicky, but very fun to play with.
