A lens which looks like an insect's honeycomb eye is attached to a camera and takes one photo. You can then, after the fact, change depth of field and even camera angle on your computer! Very cool. Here's a video from the presentation of the prototype lens. The site is in french but scroll down to the bottom and the video is in english.
I can't wait to put an Adobe Photoshop lens on my Nikon D5 !!! Crazy cool
